Alkoxide-induced nucleophilic trifluoromethylation using diethyl trifluoromethylphosphonate

A novel alkoxide-induced nucleophilic trifluoromethylation of carbonyl compounds, disulfides, and diselenides using diethyl trifluoromethylphosphonate is presented. In these reactions diethyl trifluoromethylphosphonate acts as a [CF3-] synthon.
