A method of producing an adduct of an organometallic compound M(R )3 where M is either indium or gallium and (R )3 represents a plurality of organic radicals which may be the same or different, preferably methyl or ethyl groups, comprising electrolysing, using a sacrificial anode of the metal M, a solution containing components 1 and 2 as follows: component 1: one or more organo- magnesium halide compounds R MgX where X is a halide radical selected from Cl, Br and I; where R represents one of the groups contained in (R )3; component 2: a polar aprotic liquid which is a solvent for component 1, eg tetrahydrofuran, diethyl ether, diisopentyl ether, di-n-butyl ether, diphenyl ether or anisole. Preferably, the solution electrolysed additionally contains a third component, component 3, which is one or more organic halides R XA, where R is one of the groups contained in (R )3, XA is a halide radical preferably the same as X, the polar aprotic liquid being a solvent also for component 3.
