C–H and C–F bond activation of fluorinated propenes at Rh: enabling cross-coupling reactions with outer-sphere C–C coupling

Abstract

The reaction of [Rh{(E)-CF=CHCF3}(PEt3)3] with Zn(CH3)2 results in the methylation of the alkenyl ligand to give [Rh{(E/Z)-C(CH3)=CHCF3}(PEt3)3]. Variable temperature NMR studies allowed for the identification of a heterobinuclear rhodium-zinc complex...
