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
