WebDi-tert-butyl dicarbonate is a reagent widely used in organic synthesis.Since this compound can be regarded formally as the acid anhydride derived from a tert-butoxycarbonyl (Boc) group, it is commonly referred to as Boc anhydride.This pyrocarbonate reacts with amines to give N-tert-butoxycarbonyl or so-called Boc derivatives. These carbamate derivatives do … WebPyridine is widely used as a solvent in organic chemistry and in industrial practice. Pyridine is an effective, basic solvent that is relatively unreactive, which makes it a good acid scavenger. Pyridine is the solvent of choice for acylation and dehydro-chlorination reactions.
