Abstract: A process for the direct synthesis of alkenylhalosilane monomers. Forming a slurry of liquid and copper-activated silicon from fresh silicon, cyclone fines and/or fine dust from silicon grinding, ultrafines and/or spent contact mass from the Direct Synthesis of alkylhalosilanes and arylhalosilanes, in a thermally stable solvent. Reacting the silanes by agitating the slurry with at least one unsaturated aliphatic or cycloaliphatic organohalide of the formula R1X, and optionally an organohalosilane and/or hydrogen halide, in the presence of a polymerization inhibiting Lewis base additive, at a reaction time, temperature and pressure effective to produce alkenylhalosilanes having the formulae, R1SiHX2, R12SiHX, R13SiX, R1SiX3, and R12SiX2 or mixtures thereof.

Abstract: There is provided herein a method for the manufacture of alkoxysilyl-containing thiocarboxylic acid ester which comprises reacting a thioester with a mercapto-functional alkoxysilane and/or an alkali metal salt, an alkaline earth metal salt, a trisubstituted ammonium salt of an alkoxysilyl-functional thiolate which uses economical and readily available reagents, avoids the use of phosgene or thionyl chloride reagents and produces byproducts that may be recycled.
