Conclusions The cohydrolysis of CH CSi(CH3)2OC2H5 with ClSi(CH3)2CH2Cl gave the previously unknown 1-ethynyl-3-chloromethyltetramethyldisiloxane. The bromomagnesium derivatives of the latter were reacted with CH2O, CH3COCH3, Br2, and ClSi(CH3)3. In addition, the compound was subjected to hydrosilylation, entered into the diene condensation with hexachlorocyclopentadiene, and reacted with NaI, morpholine, and piperidine.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 8, pp. 1877–1880, August, 1976. 相似文献

Previously unknown 1,1-diethylnylsilacycloalkanes (CH2)4nSi(C& = CH)2 (n = 3, 4) were prepared by the reaction of HC& = CMgBr with 1,1-dichlorosilacycloalkanes (CH2)4nSiCl2 (n = 3, 4). The reaction of (CH2)4Si(C& = CMgBr)2 with (CH2)4SiCl2 in THF under conditions of high dilution gives cyclo(tetramethylene)- silethynes [(CH2)4SiC& = C]4 with an admixture of cyclodi(tetramethylene)silethyne [(CH2)4SiC& = C]2. The re- action of Me2Si(C& = CSiMe2C& = CMgBr)2 with (CH2)4SiCl2 was used to prepare 1,1,4,4,7,7-hexamethyl-10,10- tetramethylene-1,4,4,10-tetrasilacyclododeca-2,5,8,11-tetrayne. 相似文献
