Abstract The room temperature reactions of homoleptic metalalkyl complexes with hydrogen sulfide in toluene solution have been investigated. The aluminum alkyls, AlR 3 (R = Me, Et and i-Bu), reacted with H 2 S to form air-sensitive solids which are postulated to be mixtures of Al 2 S 3 and (RAIS) n . A species of the empirical formula CH 3 GaS was produced when GaMe 3 was treated with H 2 S. Reaction
Allylic organopotassium compounds prepared by metalation of olefins with trimethylsilylmethylpotassium reacted with chlorodiethylborane and B-chloroborinane to give allylic diethylboranes and B-allylic borinanes, respectively. Hydrolysis of these organoboranes proceeding with allylic rearrangement leads to isomerized olefins. In this way, (E,Z)-2-pentene, (Z)-2-heptene, 1-methylcyclohexene and (+)-α-pinene
