Preparation of vicinal diimines: a new dehydrogenative coupling reaction of aldimines mediated by ytterbium metal
Abstract
Dehydrogenative coupling takes place to give vicinal diimine compounds in the reaction of aromatic aldimines with ytterbium metal followed by treatment with aromatic aldehydes such as 1-naphthaldehyde (1-NpCHO) as a hydrogen acceptor.
