ABSTRACT:
Organosilyl carbonates, such as bis(trimethylsilyl)carbonate, are prepared by reacting an organohalosilane with an alkali bicarbonate in the presence of an amine and/or a phosphine and an aprotic solvent, preferably a polar solvent which is inert to the reactants. The resultant mixture is separated from the ammonium halide and/or phosphonium halide and the organosilyl carbonate is recovered from the halide-free mixture.
