摘要：

Nineteen 12-, 15-, 18-, 24- and 30-membered, highly unsaturated macrocyclic silicohydrocarbons containing -SiCCSi-, (E)-SiCHCHSi- and -SiCH2CH2Si-fragments in the ring were synthesized by the reaction of Me2Si(CCMgBr)2 or BrMgCCMe2SiCCSiMe2CCMgBr with FMe2SiCH2CH2SiMe2F; (E)-FMe2SiCHCHSiMe2F or (E, E)-(ClMe2SiCHCH)2SiMe2; (E)-BrMgCCMe2Si-CHCHSiMe2CCMgBr or Me2Si(CCSiMe2CCMgBr)2 with (E, E)-(ClMe2SiCHCH)2SiMe2; and Me2Si(CCSiMe2CCMgBr)2, BrMgCCMe2-SiCCSiMe2CCSiMe2CCSiMe 2CCMgBr or BrMgCCMgBr with (E)-FMe2SiCH CHSiMe2F under conditions of high dilution. Two 20-membered and one 26-membered macrocyclic silicohydrocarbons containing 6 or 8 silicon atoms bonded by 6 or 8 CC bonds and an endocyclic CH2CH2 or CHCH bridge were obtained for the first time by treating BrMgCCMe2SiCCSiMe2CCMgBr with Cl2MeSiCH2CH2SiMeCl2 or (E)-F2MeSiCHCHSiMeF2, as well as Me2Si(CCSiMe2CCMgBr)2 with (E)-F2MeSiCHCHSiMeF2. © 1990.
