39093-93-1, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. Thiomorpholine 1,1-dioxide, cas is 39093-93-1,the Thiomorpholine compound, it is a common compound, a new synthetic route is introduced below.
A solution of 1-(bromomethyl)-3-nitrobenzene (2.400 g, 11.110 mmol), thiomorpholine 1,1-dioxide (1.427 g, 10.554 mmol) and N,N-diisopropylethylamine (2.5 16 mL, 14.442 mmol) in acetonitrile (16 mL) was stirred at the room temperature for 24 hr. Then, water was added to the reaction mixture, followed by extraction with dichloromethane. The organic layer was washed with aqueous saturated sodium chloride solution, dried with anhydrous MgSO4, filtered, and concentrated in vacuo. The residue was chromatographed (Si02, 12 g cartridge; ethyl acetate / hexane = 0 percent to 50 percent) to give 4-(3-nitrobenzyl)thiomorpholine 1,1-dioxide as yellow solid (2.800 g, 93.2 percent).
