摘要：
The invention relates to a process for preparing indium alkoxides soluble in organic solvents. The preparation method consists in reacting an indium halide with a C3-C20 alcohol in the presence of a base having a pka > 10 and a low nucleophilicity, in anhydrous medium, under inert gas and in the presence of polar organic solvents. The invention allows to obtain with a high yield pure indium alkoxides.
