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

Abstract : Cyclooctatetraene derivatives which contained alcoholic hydroxyl or dimethylamino groups attached to alkyl side chains were prepared by the copolymerization of acetylenic alcohols and an acetylenic amine with acetylene. Other cyclooctatetraene derivatives were prepared by utilizing beta- cyclooctatetraenylethyl alcohol as an intermediate. (Prepared for publication in the J. Am. Chem. Soc
