C-ACYLATION OF AZOMETHINE GROUP IN O-BENZYL AROMATIC ALDOXIMES
Baranowski, Andrzej
, p. 1993 - 1998 (2007/10/02)
Reaction of four O-benzyl aromatic aldoximes with phthalimidoacetyl chloride, 3,5-dinitrobenzoyl chloride or phthalimidoacetic-p-toluenesulfonyl anhydride in the presence of triethylamine afforded moderate yields of C-acylation products of the azomethine group.Mechanism of the reaction is discussed.
