Direct Synthesis of Trisilaalkanes

Direct Synthesis of Trisilaalkanes

A series of trisilaalkanes has been prepared in high yields by the direct reaction of ${\alpha}$ -chloromethylsilanes with metallic silicon in the presence of copper catalyst using the stirred reactor equipped with a spiral band agitator at the carefully controlled temperature between $280^{\circ}C$ and $340^{\circ}C.$ Disilaalkane compounds were obtained as the minor products. Cadmium was found to be a good promotor for the reactions, while zinc was an inhibitor.
