Preparation of adducts which may be used in the preparation of compound semiconductor materials

摘要

A method of producing an adduct of an organometallic compound M1(R1)x, where M1 is a Group II or Group III metallic element and R1)x represents a plurality of organic radicals, which may be the same or different, x being an integer equal to the valency of M1, comprises electrolysing, using a sacrificial anode of the metal M1, a solution containing components A, B and C as follows: A: a magnesium compound MgR21; B: a readily ionizable support electrolyte providing relatively large anions and cations; C: a polar aprotic liquid which is a solvent for both components A and B; the metal M1 being selected from the group consisting of: indium, gallium, cadmium.
