Rhodium complexes, Rh(L)(C2H4)2 L=(CH3C=O)2CH (acac), and (CF3C=O)2CH (hfa)}, catalyze hydrogermylation and hydrosilylation of phenylacetylene with Bu3GeH and R3SiH (R=Bu, Et), respectively, to produce Ph(R3M)C=CH2 (M=Ge, Si) selectively. Other rhodium complexes, that is, [RhCl(C2H4)2]2, Rh2Cl2(cod)2, Rh(tmhd)(C2H4)2 tmhd=(t-BuC=O)2CH}, and Rh(dbm)(C2H4)2 dbm=(PhC=O)2CH}, also catalyze these reactions, but with less regioselectivity.
铑配合物 Rh(L)(C2H4)2 L=(CH3C=O)2CH (acac) 和 (CF3C=O)2CH (hfa)} 可分别催化苯乙炔与 Bu3GeH 和 R3SiH(R=Bu、Et)的氢化锗化反应和氢硅化反应,从而选择性地生成 Ph(R3M)C=CH2 (M=Ge、Si)。其他铑配合物,即 [RhCl(C2H4)2]2、Rh2Cl2(cod)2、Rh(tmhd)(C2H4)2 tmhd=(t-BuC=O)2CH} 和 Rh(dbm)(C2H4)2 dbm=(PhC=O)2CH} 也能催化这些反应,但区域选择性较低。
