Abstract

Amination of aryl trifluoromethyl ketones with ammonium formate readily gave racemic 2,2,2-trifluoro-1-arylethylamines in good yields. Resolution of 2,2,2-trifluoro-1-phenylethylamine was carried out with the Pseudomonas fluorescens lipase via enantioselective alcoholysis of its chloroacetamide.
