Nucleophilic trifluoromethylation using trifluoromethyl iodide. A new and simple alternative for the trifluoromethylation of aldehydes and ketones.

A novel method for nucleophilic trifluoromethylation of aldehydes and ketones, based on photoinduced reduction of trifluoromethyl iodide by tetrakis(dimethylamino)ethylene (TDAE), is presented. [reaction: see text]
