Abstract The conflicting experimental data and subsequent rationalizations in the literature on tetracyclohexylsilane are critically examined. It is established that the authentic compound, obtained by hydrogenation of tetraphenylsilane, can be synthesized by organolithium condensation, although a prior report mistakenly identified an impurity-caused product, tricyclohexyl (cyclohexyloxy) silane, as such. Studies on cyclohexyllithium and ...
