ABSTRACT:
Methods for forming or purifying organometallic compounds of elements of Group III-A of the Periodic Table. An intermediate compound is formed which is an adduct of the desired organometallic compound and a Group I-A or Group II-A compound. The adduct is nonvolatile, so volatile impurities are removed from the adduct by distillation. The adduct is decomposed to release the volatile organometallic compound, which is then distilled away from the nonvolatile remainder of the adduct. The method can be used to produce organometallic compounds which are substantially free of volatile metallic compounds and complexed solvents. A method of separating volatile Group II-B impurities from volatile Group III-A compounds is also disclosed.
