PNP-type ligands showed very good property in the catalytic systems of PNP/Cr(Ⅲ)/methylaluminoxane(MAO)for ethylene selective tetramerization toward1-octene.In this research,two PNP analogues bis(diphenylphosphino)ph...
C l2M eS iS iM eC l2与环戊二烯基锂及对甲苯基溴化镁反应,生成C5H5(p-Tol)M eS iS iM e(p-Tol)C5H5.后者再与五羰基铁反应,得到标题化合物[η5,η5-C5H4(p-Tol)M eS iS iM e(p-Tol)C5H4]Fe2(CO)2(μ-CO)2(3);同时还得到两个单硅桥连...
