Abstract: Mixtures of bis(organosilyl)sulphanes (IA) and organosilyl thiocyanates (IB) of formula: (R R R SiR )xX (I) (Where: X = Sn; n = 2-20, especially 2-8 if x = 2; and X = SCN if x = 1 (thiocyanato-silane); (a) R , R , R = 1-8 carbon (C) alkyl and/or alkoxy or (b) at least one of R , R , R = alkoxy, the rest = H or monovalent aryl, especially phenyl, tolyl or benzyl; R = divalent 1-8, especially 2-4 C alkylidene or -(CH2)y-Phe-(CH2)y-; Phe = phenylene; y = 1-4.) Also claimed is a method of producing the mixtures.

Abstract: Preparation of bis(silylalkyl)disulphanes of formula (R R R SiR )2S2 (I) comprises (1) reacting silylalkyl polysulphide(s) of formula (R R R SiR )2Sn (II) with a nucleophilic compound (III) of formula M CN (IIIA), M 2SO3 (IIIB) or R R R P (IIIC) in an amount equimolar to the number of sulphur atoms to be removed from (II); (2) filtering the resultant solid; and (3) purifying (I). In the formulae, R -R , R -R = 1-8C alkyl and/or alkoxy, H or monovalent aryl, preferably phenyl, toluyl or benzyl; R = divalent 1-8C, preferably 2-4C alkylidene or a group of formula (IV); n = 3-20, preferably 3-10; and M = an alkali cation, optionally substituted ammonium ion or half alkaline earth or zinc ion. Preferably a mixture of (IIIA), (IIIB) and (IIIC) is used. Reaction is carried out in the presence of a solvent for (III) at a temperature between 20 degrees C and the b.pt. of the solvent, especially in a 2-phase system in the presence of a phase transfer catalyst.
