General description

1-Cyclohexenyl trifluoromethanesulfonate, also known as 1-cyclohexenyl triflate, is a cyclohexenyl sulfonate. Its trifluoromethylation reaction in the presence of different monodentate biaryl phosphine ligands has been investigated. The asymmetric Heck reaction of 1-cyclohexenyl trifluoromethanesulfonate using palladium complexes of phosphine oxazoline ligand has been studied.

A method for the palladium-catalyzed trifluoromethylation of cyclohexenyl sulfonates has been developed. Various cyclohexenyl triflates and nonaflates underwent trifluoromethylation under mild reaction conditions using a catalyst system composed of Pd(dba)(2) or [(allyl)PdCl](2) and the monodentate biaryl phosphine ligand (t)BuXPhos.
