Dimethylaluminum chloride which is a mild Lewis acid and a proton scavenger, catalyzes the enereactions of aliphatic and aromatic aldehydes. Proton initiated rearrangements do not occur, since the alcohol-Lewis acid complex formed in the enereaction rapidly to give methane and a non-acidic aluminum alkoxide.
