| Abstract: | Contribtions to the Chemistry of Silicon-Sulphur Compounds. XLIX. Reaction of Silicon-Sulphur Compounds with Glycols The reactions of Ph3SiSH, (RO)3SiSH, (RO)2Si(SH)2, cyclo-(t-BuO)2SiS]2, and SiS2 with aliphatic glycols were investigated. Among other compounds representatives of a new group of silanethiols (t-BuO)2Si(SH)OrOSi(SH)(OBu-t)2 (r = pr; neopent) 1 r = kohlenwasserstoffgerüst des Glykols: pr = ? CH2CH2CH2? , bu = ? CH2(CH2)2CH2? , hex = ? CH2(CH2)4CH2? , neopent = ? CH2C(CH3)2CH2? , pin = ? C(CH3)2C(CH3)2? were obtained. Informations about the hydrolytic splitting of the Si? S bond of the prepared silanethiols were obtained by thiomercurimetric titration. A pathway of the reaction of SiS 2 with glycols is discussed. |
