    trans-[Rh(CO)X(PEt3)2]1(X = Cl, Br, I or NCS) reacts with PH3 in dichloromethane at 183 K to give [Rh(CO)(PH3)2(PEt3)2]+2 which in turn reacts with CO in dichloromethane at 213 K to give [Rh(CO)2(PH3)(PEt3)2]+. The complex [Rh(CO)Cl2H(PEt3)2], formed by reaction of 1 and HCl, reacts with PH3 in dichloromethane at 219 K to give [Rh(CO)Cl(H)(PH3)(PEt3)2]+; on warming, further displacement reactions with PH3 give

    日期:1989.6
    Photocatalytic dehydrogenation of 2-propanol, yielding acetone and dihydrogen, proceeded at high turnover frequencies with carbonyl(halogeno) phosphine-rhodium complexes RhX(CO)(PR3)2 (X = halogen and PR3 = t-phosphine) under excitation conditions for the metal-to-ligand charge transfer. The three-coordinate species RhX(PR3)2 generated by photodissociation of the CO ligand was responsible for the catalytic cycle
    在激发条件下,羰基(卤素)膦-配合物RhX(CO)(PR 3)2(X =卤素和PR 3 =叔膦)以高周转频率进行2-丙醇的光催化脱氢反应,生成丙酮和二氢。用于属到配体的电荷转移。通过CO配体的光离解产生的三个配位物种RhX(PR 3)2导致了催化循环,而与配体的种类无关。电子和空间因素对膦配体的重要性都得到了证明。
