Sterically-hindered Organosilicon Compounds Containing Cyclohexyl Groups. III. Notes on Petrov and Chernysheva's Tetracyclohexylsilane and Tricyclohexyl-n-butylsilane

Discrepancies among reported melting ponints for tetracyclohexylsilane and 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 sodium butoxide with tricyclohexylchlorosilane, and it was pointed out that Petrov’s “tricyclohexylbutylsilane” is probably tricyclohexylbutoxysilane.
