Synergistic Cu-2 Catalysts for Formic Acid Dehydrogenation
Hexanuclear copper hydride complexes, [Cu-6(mu(3)-H)(2)(meso-L-4)(3)(RNC)(4)](PF6)(4) (R = 'Bu (6a), Cy (6b)), were prepared by using a new linear tetraphosphine, meso-Ph2PCH2P(Ph)(CH2)(4)P(Ph)-CH2PPh2 (meso-L-4), and were converted into active catalysts of [Cu-2(mu-O2CH)(meso-L-4)(RNC)(2)](+) under the reaction conditions of formic acid dehydrogenation, where unsymmetric dinuclear copper sites supported by the tetradentate phosphine and isocyanide ligands were essential to demonstrate effective catalytic activity.
