Alkylamidation d'organometalliques par les sels d'oxoimminium-1,3 cycliques

S. Brunel; B. Fixari; P. Le Perchec; Bernard Sillion

Abstract Dialkylcuprolithium reagents are efficiently condensed at low temperature onto N-Methyl 2-(2,4,6-trimethyl) cyclo 1,3-oxoimminium salts giving rise specifically to the corresponding alkylamides.
