Vilsmeier Reaction on Some 1-Alkyl-1-arylallyl Alcohols: Benzannulation Leading to Biphenyl-mono- and Dicarboxaldehydes
1,1-Disubstituted alkylarylallyl alcohols (2a-d) have been prepared from alkyl aryl ketones (1a-d) by Grignard reaction with vinylmagnesium bromide and subjected to the action of phosphoryl chloride in dimethylformamide under Vilsmeier reaction conditions.The biphenyl-mono- (3a-d) and dicarboxaldehydes (4a-d) formed have been readily separated and fully characterized.
