Title: PROCESS FOR THE PREPARATION OF TRIMETHYL METAL COMPOUNDS
Abstract:
Process for the production of a trimethyl metal compound with the formula M(CH3)3, said process comprising the steps of (i) reacting a metal trihalide MX3 with a trialkyl aluminium compound AI(R)3 to form a trialkyl metal compound M(R)3 and a dialkyl aluminium halide AI(R)2X, and (ii) reacting said trialkyl metal compound M(R)3 with either trimethyl aluminium [AI(CH3)3] or dimethylaluminium halide [AI(CH3)2X] to form said trimethyl metal compound M(CH3)3, wherein M is selected from the group consisting of Ga and In, X is a halogen, and R is a linear or branched alkyl group with 2 to 8 carbon atoms.
