PECULIARITIES OF THE REVERSIBLE ACID-CATALYZED TRANSAMIDATION OF THE N-ETHYLANILIDE OF NEOPENTYLENEPHOSPHORIC ACID

Nifant'ev, E. E.,Grachev, M. K.,Burmistrov, S. Yu.,Vasyanina, L. K.

, p. 2013 - 2017 (2007/10/02)

We studied the kinetics of diethylaminolysis of the N-ethylanilide of neopentylenephosphoric acid in the presence of diethylamine hydrochloride under reversible reaction conditions.A strongly passivating effect of the association of reactants on the transamidation of the amides of P(III) acids was observed.
