Herein, we report a straightforward, environmentally friendly, and controllable palladium/ligand catalytic system to enable reductive/oxidative Heckreactions of cyclic enones with thiophene or furan derivatives via C-H activation. The key to this tunable reaction is the appropriate intercepting thienyl-Pd(II)-enolate during the enolization process. Such a controllable and economic protocol would not

The enantioselective 1,4-addition of 2-(substituted)thienylzinc and 2-furanylzinc reagents has been achieved (up to 99 : 1 er) using a complex derived from [Rh(C2H4)2Cl]2 and Me-DUPHOS.
