Process for producing sulfur-containing organosilicon compounds and synthetic intermediates thereof

摘要

An object of the present invention is to provide a method of obtaining high-purity sulfur-containing organosilicon compounds having polysulfide structure in a simple manner without treatment at high temperatures or under vacuum. According to the present invention, sulfur-containing organosilicon compounds represented by the formula (R1-O)3-Si-R2-Sx-R2-Si-(O-R1)3 is obtained by reacting sulfur, an alkali metal and halogenoalkoxysilane represented by the formula (R1-O)3-Si-R2-X (wherein R1 is a monovalent C1-5 hydrocarbon, R2 is a divalent C1-9 hydrocarbon, X is a halogen, and x is an integral number of 1 to 8).
