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
chance to develop new catalytic systems before empirical studies were undertaken. Then the iridium-catalyzed domino hydroformylation/reduction of olefins to alcohols under water–gas shift reaction conditions was studied as an example. Two different ligands (L1 and L10) applied at the same time improved alcohol yields and verified the computational model.
