trichloroacetyl compounds following the modification of Appel’s reaction protocol, using triphenylphosphine and methanol, afforded the corresponding dichloroacetyl compounds, with the exception of trichloroacetylmorpholine, in yields of 80–98% under very mild experimental conditions. Likewise, when trichloromethyl heterocyclic compoundscontain another reactive functional group, the reaction is highly chemoselective
