Neue Methode zur reduktiven Desaminierung primärer aliphatischer Amine

open access: yesCHIMIA, 1988
A new method for reductive deamination of primary aliphatic amines via tributyltin hydride reduction of aromatic imidoyl chlorides is reported. Good yields of hydrocarbons were obtained from benzylamines and cyclohexylamine, but not from 1-alkylamines.
