THE METHOD OF REDUCING A REDUCIBLE ORGANOMETALLIC COMPOUND CONSISTING ESSENTIALLY OF ADMIXING (A) AN ORGANOSILICON COMPOUND CONTAINING AT LEAST SOME HYDROGENN BONDED TO SILICON ATOMS BY H-SI BONDING SELECTED FROM THE GROUP CONSISTING OF ORGANOHYDROGENHALOSILANES, LOW MOLECULAR WEIGHT CYCLIC ORGANOHYDROGENSILOXANES AND ORGANIC SOLVENT SOLUBLE LINEAR ORGANOHYDROGENSILOXANES HAVING VISCOSITES IN THE RANGE FROM 5 CS. TO 10,000,000 CS. AT 25*C. WHEREIN THE ORGANIC SUBSTITUENTS ARE MONO-NOVALENT HYDROCARBON RADICALS, (B) AN ORGANIC SOLVENT MEEDIUM SELECTED FROM THE GROUP CONSISTING OF ALCOHOLS AND LIQUID HYDROCARBONS, (C) AN ACTIVE HYDROGEN DONOR SELECTED FROM THE GROUP CONSISTING OF WATER, ALCOHOLS AND FATTY ACIDS, AND (D) AN ORGANOMETALLIC COMPOUND SELECTED FROM THE GROUP CONSISTING OF ORGANOMETALLLIC COMPOUNDS OF TIN, MERCURY, IRON, COPPER, TITANIUM, NICKEL, ZIRCONIUM, ALUMINUM, ZINC, LEAD AND CADMIUM, SAID ORGANOMETALLIC COMPOUND BEING SOLUBLE IN THE ORGANIC SOLVENT MEDIUM (B), AND HEATING THE MIXTURE TO A TEMPERATURE IN THE RANGE FROM ROOM TEMPERATURE TO THE REFLUX TEMPERATURE OF THE MIXTURE.
