trialkylchlorosilanes can readily be synthesized by the reaction of alkoxysilanes, silanols, and hydrosilanes with aqueous concentrated hydorochloric acid. Treatment of trialkylalkoxysilanes bearing the bulky alkyl substituents, such as the i-Pr, sec-Bu, tert-Bu, and cyclo-Hex group, with 35% aqueous hydrochloric acid afforded the corresponding trialkylchlorosilanes in excellent yields. Similar treatment of trialkylsilanols
The reduction of derivatives of the type RnSiσ4-n (σ = Cl, OCH3) by some organomagnesium compounds RMgX at high temperature (⩾80°) leads to the hydrosilanes RR'SiH2 and RR'2SiH in various ratios according to the considered reagents. The results described in this publication constitute a first approach in the knowledge of the mechanism of these reductions. A deeper study of the mechanism is the subject

Herein we report on a series of bulky bis(alkyl)‐ and bis(silyl)‐ substituted polysilanes. Moreover, we performed desilylation and dechlorination experiments with them. These compounds were characterized by multinuclear NMR spectroscopy, mass spectrometry, and X‐ray crystallography. It was found that the selective formation of silyl mono‐ and di‐anions is crucial for the successful isolation of these

tricyclohexylbutylsilane were discussed. Tricyclohexylcyclohexoxysilane was obtained in 2∼5% yield in addition to tricyclohexylchlorosilane from the reaction of cyclohexyllithium with silicon tetrachloride. Petrov’s compound melting at 198°C is most likely to be tricyclohexylcyclohexoxysilane and not a stereoisomeric tetracyclohexylsilane. Tricyclohexylbutoxysilane, m. p. 133°C, was prepared by treating
chloride proceeds by two simultaneous processes: the direct reduction by the organomagnesium compound and the indirect reduction by the magnesium hydride coming from the thermic decomposition of the Grignardreagent. These results can be generalised to the reductive action of various sterically hindered Grignardreagents: R=C6H11, C5H9, i-C3H7.
在温度> 100°时,叔丁基氯化镁将R 3SiΣ型三有机硅烷(ΣCl或OCH 3)转化为氢硅烷R 3 SiH的过程同时进行两个过程:有机镁化合物的直接还原和间接的格氏试剂的热分解导致氢化镁还原。这些结果可以推广到各种空间受阻的格氏试剂的还原作用:R = C 6 H 11,C 5 H 9,iC 3 H 7。
