A METHOD OF PRODUCING ORGANOSILANES THAT COMPRISES CONDUCTING, IN THE PRESENCE OF AN ALUMINUM HALIDE IN WHICH EACH HALOGEN ATOM HAS AN ATOMIC WEIGHT BEING 35 AND 80, A CONDENSATION REACTION IN WHICH A HYDROGEN HALIDE IS FORMED BY SPLITTING OUT A HALOGEN ATOM HAVING AN ATOMIC WEIGHT BETWEEN 35 AND 30 FROM A HALO-SUBSTITUTED SATURATED ALIPHATIC HYDROCARBON RADICAL THAT IS CONNECTED DIRECTLY TO A SILICON ATOM IN A HALO-SUBSTITUTED ORGANOSILICON COMPOUND, AND BY SPLITTING OUT A NUCLEAR HYDROGEN ATOM FROM AN AROMATIC COMPOUND, ALL SAID CONDENSATION REACTION BEING CONDUCTED BY BRINGING TOGETHER SAID ALUMINUM HALIDE AND SAID REACTANTS, THE CARBON ATOMS IN THE MOLECULES FROM WHICH SAID HYDROGEN AND HALOGEN ATOMS ARE SPLIT OUT BEING CONTIANED IN AROMATIC NUCLEI AND SATURATED ALIPHATIC RADICALS, AND THOSE WHICH ARE CONNECTED TO SILICON BEING ALIPHATIC CARBON ATOMS, AND ANY ATOM IN SAID MOLECULES OTHER THAN CARBON, HYDROGEN, HALOGEN AND SILICON CONSISTING OF AN OXYGEN ATOM CONNECTED TO SILICON, ANY ATOM THAT IS CONNECTED TO SUCH AN OXYGEN ATOM, OTHER THAN SILICON ATOMS, AND CARBON ATOMS CONTAINED IN AROMATIC NUCLEI AND SATURATED ALIPHATIC RADICALS, CONSISTING OF A HYDROGEN ATOM.
