which showed an unusually short cross-ring Si–Si distance in the 4-membered ring. The reactivities of the cyclic bis(organosilyl)bis(t-butyl isocyanide)palladium complexes toward phosphines, cyclic disilanes, and alkynes were also examined. Cyclic organosilicon compounds were synthesized by bis-silylation of alkynes with cyclic bis(organosilyl)palladium intermediates generated by the intramolecular metathesis
通过将环状乙硅烷氧化加成到双(叔丁基异氰化物)钯 (0) 上以及通过分子内两个 Si-Si 键的复分解作用合成四至七元环状双(有机甲硅烷基)钯(II)配合物。双(乙硅烷)与钯(0)络合物。2,2-双(1,1,2,2-四甲基-2-苯基二硅烷基)-1,3-二噻烷制备的4元双(有机甲硅烷基)双(叔丁基异氰)钯配合物-晶体 X 射线方法,显示 4 元环中的跨环 Si-Si 距离异常短。还检查了环状双(有机甲硅烷基)双(叔丁基异氰化物)钯配合物对膦、环状乙硅烷和炔烃的反应性。环状有机硅化合物是通过炔烃与分子内复分解产生的环状双(有机甲硅烷基)钯中间体的双甲硅烷基化合成的。双甲硅烷基化也适用于缺电子烯烃:α,β-不饱和酮得到 7 元 1,4-双甲硅烷基...
