The Palladium-Catalyzed Trifluoromethylation of Vinyl Sulfonates
摘要:
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 [(ally1)PdCl](2) and the monodentate biaryl phosphine ligand (t)BuXPhos. The trifluoromethyl anion (CF3-) or its equivalent for the process was generated in situ from TMSCF3 in combination with KF or TESCF3 in combination with RbF.
