Preparation of organometallic indium and gallium compounds.

摘要

A method of producing an adduct of an organometallic compound M(R<Sup>1</Sup>)<Sub>3</Sub> where M is either indium or gallium and (R<Sup>1</Sup>)<Sub>3</Sub> 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:
<UnorderedLists id="ula01" listStyle="none"><ListItem>component 1: one or more organomagnesium halide compounds R'MgX where X is a halide radical selected from CI, Br and I; where R<Sup>1</Sup> represents one of the groups contained in (R<Sup>1</Sup>)<Sub>3</Sub>;</ListItem><ListItem>component 2: a polar aprotic liquid which is a solvent for component 1, eg tetrahydrofuran, diethyl ether, di-isopentyl ether, di-n-butyl ether, diphenyl ether or anisole.</ListItem></UnorderedLists>

Preferably, the solution electrolysed additionally contains a third component, component 3, which is one or more organic halides R<Sup>1</Sup>X<Sub>A</Sub>, where R<Sup>1</Sup> is one of the groups contained in (R<Sup>1</Sup>)<Sub>3</Sub>, X<Sub>A</Sub> is a halide radical preferably the same as X, the polar aprotic liquid being a solvent also for component 3.
