The molecular association of small organosilicon heterocycles and their analogs

摘要: The molecular association of derivatives the 1-silacycloalkanes CH2(CH2)n−1SiXY and their saturated unsaturated noncyclic analogs has been studied by cryoscopy in cyclohexane. It established that this series heterocycles tendency to falls with an increase size is a maximum case silacyclobutanes (n=4). Derivatives 1-silacyclobutane are associated considerably more strongly than CH2=CH(CH3)XiXY CH3CH2(CH3)SiXY. relationship found between degree structure harmony results studies UV spectroscopy also data on reactivities.
