Article abstract of DOI:10.1016/S0040-4020(01)89174-2

The reaction of a series of the title anilines (1) with variously substituted benzyl groups under Vilsmeier conditions was invesigated.Only perfluorobenzyl derivatives showed normal formylation while other fluoro derivatives gave mixed results and other substituents gave solely the anomalous amine (5) together with the aldehyde (6) derived from the benzyl group.
