Trialkylgallium is prepared by reacting a gallium halide or alkyl gallium with trialkylaluminum in a solvent having a boiling point which is at least 10° C. higher than the boiling point of the trialkylgallium, such as mesitylene or o-dichlorobenzene. High purity alkyl gallium is obtained in high yields.
