Reactions of carbocyclic, heterocyclic, and steroidal ketones with benzylamine and diethyl phosphite in a catalytic three-component “one-pot” synthesis of α-amino phosphonates were studied. The activities of mono-and binuclear complexes of tetra(tert-butyl)phthalocyanines as catalysts for this process were compared.

reaction mixture, two nucleophiles: dialkyl phosphite and the amine compete for the electrophilic carbonylcompound. Reaction mixture composition studies, kinetic studies as well as theoretical calculations, indicate that the softer the carbonylcompound is, the faster it reacts with the softer phosphorus nucleophile and the slower it reacts with the harder amine nucleophile. It in turn results in
A variety of organophosphates are synthesized from n-BuLi-triggered, (additional) solvent-free reactions of diethyl phosphite with both activated/unactivated ketones and aldehydes preferably at room temperature via phospha-Brook rearrangement. We could successfully synthesize the naphthylic/allylic phosphates using this approach. (C) 2015 Elsevier Ltd. All rights reserved.

In a Kabachnik-Fields synthesis of aminophosphonates amines can catalyse the formation of hydroxyphosphonates, and their further rearrangement to phosphates, unabling the formation of aminophosphonates.
