The cross-coupling reactions of 1,1,1-trifluoro-2-iodoethane with aryl and heteroaryl boronic acid esters have been successfully achieved. The new protocol allows for a convenient introduction of trifluoroethyl groups into a variety of aryl and heteroaryl moieties under mild conditions.
This research provides a novel approach for introducing a CF3CH2 group onto aromatic rings using Pd(OAc)2/palladacycle as a catalyst for the Suzukicross-couplingreaction of CF3CH2OTs (OTs = 4-methylbenzene sulfonate) with arylboronicacids.
