Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 616-14-8, is researched, Molecular C5H11I, about Synthetic methods and reactions. 63. Pyridinium poly(hydrogen fluoride) (30% pyridine-70% hydrogen fluoride): a convenient reagent for organic fluorination reactions, the main research direction is fluorination pyridinium polyhydrogen fluoride; diazotization fluorination; safety pyridinium polyhydrogen fluoride.SDS of cas: 616-14-8.

Pyridinium polyhydrogen fluoride (30% pyridine-70% HF) reagent, a stabilized, less-volatile form of HF, is a convenient and effective fluorinating agent. Fluorination, halofluorination, nitrofluorination, and hydrofluorination of olefins were achieved using the reagent. The in situ diazotization and subsequent fluorinative dediazonization of α-amino acids, aminoarenes, and carbamates yielded α-fluorocarboxylic acids, aryl fluorides, and fluoroformates, resp. Geminal dihalides and α-halo ketones were treated with HgO in pyridinium polyhydrogen fluoride to form geminal difluorides and α-fluoro ketones. Solutions of alkali halides in pyridinium polyhydrogen fluoride were also effective halogenating agents for aminoarenes, via in situ diazotization and subsequent nucleophilic dediazonization by the corresponding halides, as well as for alcs., via SN2 displacement reactions. Diazo ketones and diazoalkanes also reacted smoothly with halide ions in pyridinium polyhydrogen fluoride solution to give the corresponding geminally halofluorinated compounds Proper precautions must be observed in using pyridinium polyhydrogen fluoride.

Substances of the type MeCH[(CH2)n1X][(CH2)n2R], where n1 or n2 = 0 or an integer, X = a functional group and R = a normal alkyl, Ph or C6Hn group, can be classified into 2 categories, viz., those, typified by X = CHO, in which the configuration of the 1st members having n1 = 0 can be correlated by classical methods to those having n1 > 0, and those, typified by X = halogen, in which such correlation cannot be accomplished by classical methods. For the purpose of solving the latter problem the azides were chosen over the halides, inasmuch as they can be converted into the corresponding amines. The amines, while belonging to the 2nd category, can be correlated among themselves by a sufficiently reliable though nonclassical argument which will be reported later. The secondary azides were prepared by the action of NaN3 on the iodides and the amines by reduction of the azides with PtO2. The rotatory phenomena observed in the series of azides and halides were compared with those in the series of aldehydes and were found to be dissimilar in both series. Hence a comparison of these phenomena cannot be used for the correlation of the members of the series of halides and azides having n1 = 0 with those having n1 > 0.
