Convenient one pot preparation of acylated phosphinimines and aminophosphonium salts from the versatile triphenylphosphonium and lithium azayldiide Ph3P=N-Li

Starting from gaseous ammonia, through two multisteps reactions, either acylation or alkylation reactions, we have access to different N-substituted aminophosphonium salts, precursors of amines. Preparation and use of the intermediate, the triphenylphosph

Alkylation et acylation de la triphenylphosphinimine N-lithiee

A new synthetic approach to primary and secondary amines using N-lithiated triphenylphosphinimine is reported.This key reagent, accessible in two steps from dibromortiphenylphosphorane and ammonia, when treated with electrophiles yields N-substituted triphenylphosphinimine derivatives.These can react to give N-mono or disubstituted triphenylphosphonium salts which upon hydrolysis lead to the corresponding primary and secondary amines.
