Iodine monobromide is an extremely effective catalyst for the redistribution of alkoxyl groups on silicon atoms in dimethyldiakoxysilanes. The equilibrium constants of these reactions were determined at 40 °C by means of gas chromatography. Assuming that the reaction intermediate is the dative form of a dimethyldialkoxysilane–iodine monobromide complex, a mechanism of the reaction was proposed.
