cf. C. A. 22, 1953. The conclusion that in the aliphatic series the carbinols and the structurally related halides rotate in opposite directions is substantiated by the study of a series of aliphatic substances derived from disubstituted acetic acids or their corresponding carbinols. Primary halides rotate in the opposite direction to the primary alcs. from which they were derived, while in passing from the corresponding thio to the sulfo derivative the change in rotation is in the same direction, though without change of sign. A decided uniformity was found in the effect on optical rotation of various substitutions of the CO2H group or of the alc. group of the corresponding carbinols, depending upon the position of the subsituting group in the polarity series, C = N > CO2Et > CO2H > CONH2 > COCl > CH2SO3H > CH2X > CH2SH > CH2OH > CH2NH2. The order in this series corresponds with the order of the same groups in polarity series determined by other methods. This relationship holds only for aliphatic substances containing only 1 asym. C atom and only 1 polar group. Active primary amyl alc. was halogenated without marked racemization, while in the rest of the series conversion to the halide from the carbinol by SOCl2, PCl5, HBr, HI, etc., as well as from the amine by NOCl2, led to complete racemization.

Decrypt The Mystery Of 616-14-8

《Radical Yields in the Radiolysis of Branched Hydrocarbons: Tertiary C-H Bond Rupture in 2,3-Dimethylbutane, 2,4-Dimethylpentane, and 3-Ethylpentane》 provides a strategy for the preparation of materials with excellent comprehensive properties, which is conducive to broaden the application field of this compound(1-Iodo-2-methylbutane)Name: 1-Iodo-2-methylbutane.

Name: 1-Iodo-2-methylbutane. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 1-Iodo-2-methylbutane, is researched, Molecular C5H11I, CAS is 616-14-8, about Radical Yields in the Radiolysis of Branched Hydrocarbons: Tertiary C-H Bond Rupture in 2,3-Dimethylbutane, 2,4-Dimethylpentane, and 3-Ethylpentane. Author is Schuler, Robert H.; Wojnarovits, Laszlo.

Gel permeation chromatog. has been applied to iodine scavenging studies of the distribution of radicals produced in the radiolysis of sym. branched hydrocarbons 2,3-dimethylbutane, 2,4-dimethylpentane, and 3-ethylpentane. The principal iodides observed are those expected as a result of simple bond rupture. In the case of 2,3-dimethylbutane all five expected iodides are readily resolvable and it is shown that the loss of H from a tertiary position is favored over loss from a primary position by a factor of ∼10. A similar ratio is also observed for 2,4-dimethylpentane. The higher ratio of 15 observed for 3-ethylpentane indicates a dependence on the number of tertiary sites on the alkane. The relative yield of ∼3.3 for the loss of secondary and primary H atoms from 2,4-dimethylpentane and 3-ethylpentane is similar to that for normal alkanes, indicating a negligible effect of the adjacent tertiary carbon. In all three cases the rupture of terminal C-C bonds is relatively infrequent with C-C rupture occurring preferentially at the bonds adjacent to the tertiary carbon.

Sorption of MeBr on groundnuts (I) was studied with both undecorticated I and I separated into husk, cotyledon, and germ. Successful treatment of I with MeBr depended on the moisture content of the nuts. Impairment of germination following MeBr treatment was observed when the moisture content exceeded 5%. Sorption of MeBr was found to increase more rapidly than the dosage, necessitating careful dosage control. At concentrations lower than that critical for a particular moisture content and period of fumigation, a slight stimulating action of MeBr on germination was observed.

Formula: C4H6N4O2. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 1-Methyl-4-nitro-1H-imidazol-5-amine, is researched, Molecular C4H6N4O2, CAS is 4531-54-8, about Nitroarylamines via the Vicarious Nucleophilic Substitution of Hydrogen: Amination, Alkylamination, and Arylamination of Nitroarenes with Sulfenamides. Author is Makosza, Mieczyslaw; Bia-lecki, Maciej.

A new reaction of sulfenamides with electrophilic arenes under basic conditions is described. The σ adducts formed from nitroarenes and the anions of sulfenamides undergo elimination of thiol to produce the corresponding o- and/or p-nitroanilines. This reaction is analogous to the known alkylation and hydroxylation of nitroarenes via the vicarious nucleophilic substitution of hydrogen (VNS). The reaction gives access to a wide range of substituted nitroanilines, nitronaphthylamines, and aminoheterocycles. By means of the reaction with N-alkyl- and N-arylsulfenamides, it is possible to obtain N-alkylnitroanilines and nitrodiarylamines. By varying the structure of sulfenamide and the reaction conditions, particularly the nature and concentration of the base, it is possible to control the orientation of amination.

The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Asymmetric reductions. VI. The action of the Grignard reagent from (+)-1-chloro-2-methylbutane on a series of alkyl tert-butyl ketones》. Authors are Foley, William M.; Welch, Frank J.; Combe, Edward M.

cf. C.A. 51, 1828h. Title reactions were carried out with six ketones, and the % asymmetric reduction, i, was determined by comparing the observed rotation of each resulting carbinol with the maximum rotation of pure isomers obtained by resolution. The absolute configurations of the prepared carbinols were determined and R, [α]25D (neat), and i were as follows: Me, 0.63°, 13.4; iso-Pr, -0.38°, 4.6; Et, -2.94°, 10.7; Pr, -3.87°, 11.3; Bu, -3.78°, 11.0; and iso-Bu, -2.56°, 5.9. The results agreed with a reaction mechanism of Grignard reduction involving an intermediate cyclic six-membered transition state in which stereospecificity was controlled by steric interaction of the alkyl and tert-butyl groups of the ketones and the Me and Et groups of the Grignard reagent. The alkyl tert-butyl ketones were prepared by coupling the appropriate acid chloride, RCOCl, with the Grignard reagent from freshly distilled tert-BuCl in the presence of Cu2Cl2 to yield the following products (R, % yield based on Grignard reagent, b.p., and n25D given): Me, 33, 105.2°, 1.3974; Et, 89, 125.0-5.8°, 1.4049-51; Pr, 63, 145.0-5.8°, 1.4109-11; iso-Pr, 36, 135.2-6.7°, 1.4049-68; Bu, 69, 167.0-9.0°, 1.4149-59; and iso-Bu, 40, 155.5-7.0°, 1.4135-42.

Strychnine was used in the resolution and eventually (+)-VII was obtained, m. 75.6-7.5°, [α]23D 8.7° (c 1.5, CHCl3), hydrolyzed to (+)-VI, m. 40-1°, α26D 57.5° (c 20.4, MeOH), and α23D 54.5° (neat, by extrapolation of rotation-concentration curve); acetate of (+)-VI b17 73°, α22D 15.15° (neat, l 0.5), n20D 1.4176, d22 0.852; benzoate of (+)-VI b0.6 88°, α25D 8.24° (neat, l 0.5), n20D 1.4870, d25 0.955. Racemic tert-BuCHBuOH (VIII), n20D 1.4320, was converted to acid phthalate (IX), m. 100.5-2.0°, and then to the strychnine salt. The regenerated (+)-IX was a glass, α23D 4.5° (c 2.8, CHCl3), which was saponified to (+)-VIII, n20D 1.4314, α24D 17.10° (neat, l 0.5). The (-)-phthalate from the more soluble fractions of strychnine salt gave (-)-VIII, α24D -16.39° (neat, l 0.5). The dl-tetrachlorophthalate of VIII was also prepared, m. 126-8°, converted to the strychnine salt, and the less soluble form, [α]25D -12°, hydrolyzed to (-)-acid tetrachlorophthalate, α22D -9.69°, which was saponified to (+)-VIII, α22D 13.70° (neat, l 0.5); 3,5-dinitrobenzoate (X) of (+)-VIII m. 107.5° (MeOH), α25D 10.0° (c 2.4, CHCl3); 3,5-dinitrobcnzoate of dl-VIII, m. 84.0-4.5°. X was saponified to (+)-VIII, b23 76°, α25D 17.12° (neat, l 0.5), n20D 1.4310, d26 0.823. The value for pure (+)-VIII was taken as α25D 34.24° (neat, l 1). From (-)-VIII, α25D -32.8° (neat, l 1), was prepared: acetate, b20 87°, α26D -11.25° (neat, l 0.5), n20D 1.4191, d26 0.851; benzoate, b0.5 98°, α25D -7.29° (neat, l 0.5), n20D 1.4887, d25 0.936; p-nitrobenzoate, b0.5 144-5°, α29D -12.50°, n25D 1.5070. Some work was done with the Grignard reagents of the following prepared compounds: (+)-1-bromo-2-methylbutane, b100 60.8°, n20D 1.4453, α24D 4.22° (neat, l 1), 84% optical purity, a 2nd preparation b100 57-8°, α26.6D 4.66°, 93% optical purity; and (+)-1-iodo-2-methytbutane, n20D 1.4955-69, α21D 8.65° (neat, l 1), 98.5% optical purity, 2nd preparation b53 70°, n20D 1.4969-72, α25D 16.8° (neat, l 2), optical purity 96.5%.

Synthetic Route of C5H11I. The fused heterocycle is formed by combining a benzene ring with a single heterocycle, or two or more single heterocycles. Compound: 1-Iodo-2-methylbutane, is researched, Molecular C5H11I, CAS is 616-14-8, about On labeling with generator nuclides. Author is Otto, R.; Hecht, P..

Short-lived radioisotopes separated from radionuclide generators are widely used. The possibilities of labeling with the daughter nuclides of the com. available Mo/Tc-, Sn/In- and Te/I- generators and of the self-made Ba/La-generator in industrial tracer experiments are presented. The transfer of the daughter nuclides from the generator eluates into organic phases and the labeling of oil-phases and solid particles were investigated. The simple, quick, and efficient methods developed are suitable for routine application under industrial conditions. Some examples of industrial applications of the generator nuclides are given.
