PHOSPHORYLATION OF ALCOHOLS AND AMINES WITH AMIDES OF THREE-VALENT PHOSPHORUS ACIDS. ACHIEVEMENTS AND PROBLEMS

By Mikhail Konstantinovich Grachyev

Abstract

The study on the alcoholysis mechanism of the phosamides in presence of the amine hydrochlorides has been performed firstly with strong attachment of the kinetic data and data about behaviour of the supposed intermediate, the fact of the general acid process catalysis has been determined. The influence of the catalytic diethylamine hydrochloride additions on the re-amidation rate has been studied. The influence of the mutual orientation of the hydroxyl groups and other factors on the regional direction of the phosphorylation has been studied firstly as an example of the diols. The proposals on the use of this method in the synthetic practice have been developed on base of the fundamental investigation on the acid-catalysis phosphorylation of the alcohols and amines with the acide amides of the three-valent phosphorus. The amides and azolides of the three-valent phosphorus acids have been shown as effective phosphorylating aids for the oligo- and polyhydroxyl-containing compounds - cyclodextrins, chitozan and cellulose.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
