derivatives of the transition metals have been synthesized, LMCH2SiMe2SiMe3 [LM = (η5-C5R5) M(CO)n−, M = Fe, W, R = H, Me, n = 2, 3; (η5-C9H7)Fe(CO)2−; (η5-C5H5) 2MCl−, M = Ti,Zr,Hf]. The cyclopentadienylcarbonyl complexes are photochemically labile with respect to rearrangement to LM-SiMe2 CH2SiMe3 and are also subject to base-induced migration to the cyclopentadienyl ring to form (η5-Me3SiCH2SiMe2C5H4)
摘要合成了过渡金属的五甲基二甲硅烷基甲基衍生物,LMCH2SiMe2SiMe3 [LM =(η5-C5R5)M(CO)n-,M = Fe,W,R = H,Me,n = 2,3; (η5-C9H7)Fe(CO)2- (η5-C5H5)2MCl-,M = Ti,Zr,Hf]。环戊二烯基羰基配合物在重排成LM-SiMe2 CH2SiMe3方面在光化学上不稳定,并且还受到碱诱导的迁移到环戊二烯基环上以形成(η5-Me3SiCH2SiMe2C5H4)衍生物。钛,锆和ha的络合物均不显示任何性质。从这些配合物的光化学处理中分离出的唯一化合物是Me3SiSiMe3。介绍了(η5-C5H5)W(CO)3 CH2SiMe2SiMe3及其膦取代的重排产物(η5-C5H5)W(CO)2(PPh3)SiMe2CH2SiMe3的结构分析。
