本文报道用相转移催化作用合成异核金属簇络合物的新方法。在研究Co_2(CO)_8与Pt[P(C_6H_5)_3]_2Cl_2的反应时,除了得到异核金属簇Pt_2Co_2(μ_2-CO)_3(CO)_5[P(C_6H_5)_3]_2外,还分离出一种新的异核金属簇Pt_3Co_2(μ_2-CO)_5(CO)_4[P(C_6H_5)_3]_3和五核铂簇Pt_5(μ_2-CO)_5(CO)[P(C_6H_5)_3]_4. 考察了Pt_2Co_2(μ_2-CO)_3(CO)_5[P(C_6H_5)_3]_2对1-己烯的催化醛化活性,发现它是一种在温和条件下,有较高活性的催化剂。
This paper reports a new method for the synthesis of heteronuclear metal cluster complexes by phase transfer catalysis. In addition to obtaining Pt_2Co_2 (μ_2-CO) _3 (CO) _5 [P (C_6H_5) _3] _2 at the reaction of Co_2 (CO) _8 with Pt [P (C_6H_5) _3] _2Cl_2, A new cluster of Pt_3Co_2 (μ_2-CO) _5 (CO) _4 [P (C_6H_5) _3] _3 and Pt_5 (μ_2-CO) _5 (CO) [P (C_6H_5) _3] _4. The catalytic hydroformylation of 1-hexene with Pt_2Co_2 (μ_2-CO) _3 (CO) _5 [P (C_6H_5) _3] _2 was investigated and found to be a catalyst with higher activity under mild conditions .
