5-trioxacyclohexane < ethanol < isobutane < THF < Etsub3}SiH. The observed selectivities generally parallel those for homodimerization, reported in the preceding paper, but certain differences are noted, and reasons for the differences are proposed. The bond-dissociation energymore » of Etsub3}SiH is estimated from the reactivity data to be 90 kcal/mol. Eleven new carbinols are synthesized. 39 refs., 6 tabs
