Abstract
The room temperature reactions of homoleptic metal alkyl complexes with hydrogen sulfide in toluene solution have been investigated. The aluminum alkyls, AlR 3 (R = Me, Et and i-Bu), reacted with H 2S to form air-sensitive solids which are postulated to be mixtures of Al 2S 3 and (RAIS) n . A species of the empirical formula CH 3GaS was produced when GaMe 3 was treated with H 2S. Reaction of Cd(CH 2SiMe 3) 2 with H 2S yielded cadmium sulfide which retained approximately 10 ppm of the alkyl group. At room temperature, Hg(CH 2SiMe 3) 2 was unreactive with H 2S. However at 150 °C the neat liquid reacted to form highly crystalline mercuric sulfide in the cubic crystalline form. The reactions of MgEt 2 and Ti(CH 2SiMe 3) 4 with H 2S are also described.
