The synthesis of the potential bridging ligand (C6H5)2PCH2CH2Si(CH3)2C5H4 (3) is described. The ferrocene (6 derived from 3 has been found to form macrocyclic complexes with metal fragments NiCl2, NiBr2, and Co2(CO)6. Although monomeric, bimetallic products might have been expected basedupon the reduced steric demands of ligand 3 relative to an analogous ligand, (C6H5)2PCH2Si(CH)3)2C5H4 (1), it appears
描述了潜在桥联配体(C 6 H 5)2 PCH 2 CH 2 Si(CH 3)2 C 5 H 4(3)的合成。二茂铁(由3衍生而来的6被发现与金属碎片NiCl 2,NiBr 2和Co 2(CO)6形成大环络合物。尽管由于配体3相对于3与类似的配体(C 6 H5)2 PCH 2 Si(CH)3)2 C 5 H 4(1),似乎3的增加的柔韧性是压倒一切的因素,导致优先选择6的第二膦功能的分子间配位,而不是分子内配位。

The complexes (Ph3P)(R3E) PtPPh2(CH2)(n)SiR21 (n = 2: R' = Me: ER3 = SiPh3, SiMePh2, SnPh3; R' = Ph: ER3 = SiPh3, SiMePh2; n = 1, R' = Me, ER, = SiPh,) are obtained by reaction of Ph2P(CH2)(n)SiR'2ER3 with (Ph3P)(2)Pt(pi-C2H4). The bis(silyl) complex (Ph3P)(Ph2Si)PtPPh2CH2SiMe2 was characterized by an X-ray structure analysis, which showed the two silyl groups to be cis (Pt-Si 236.8(1) and 237.4(1) pm).
