Organosilicon sulfides of the type= SiCH2SR were obtained by the reaction of the corresponding chlorosubstituted silane or siloxane with sodium mercaptides. The corresponding sulfones may be prepared by oxidizing the sulfides with hydrogen peroxide in acetic acid, if siloxane bonds are not present; the sulfone derivatives of the siloxanes were obtained when monoperphthalic acid in ether is used as the oxidizing agent. The sulfones ...
