Abstract: PROBLEM TO BE SOLVED: To obtain the subject mixture useful for the production or the like of a vulcanizable plastic-rubber mixture by reacting a silylorganylpolysulfane or the like with a metallic cyanide compound and then reacting the resultant compound with a halogenalkylalkoxysilane. SOLUTION: A silylorganylpolysulfane (mixture) represented by formula I R to R are each a 1-8C alkyl and/or a 1-8C alkoxy group in which at least one thereof is the alkoxy group; R is a 1-8C bivalent alkylidene or a group represented by formula II [(y) is 1-4]; (n) is 2-20} is reacted with a nucleophilic compound represented by the formula M CN [M is an alkali metallic cation, a (substituted)ammonium ion, a half alkaline earth metallic ion or zinc ion] and the resultant compound is then reacted with a compound represented by formula III at a high temperature under a high pressure to afford a mixture of a bis(silylorganyl)polysulfane represented by formula IV [X is Sn when (x) is 2 and X is SCN when (x) is 1] with a silylorganyl thiocyanate useful as a phase transfer assistant or the like for incorporating an acidic substance in a rubber matrix for the production or the like of a vulcanizable mixture.

Abstract: PROBLEM TO BE SOLVED: To produce the subject new high-purity compound useful for the production or the like of tires by reacting elementary sulfur with an anhydrous sulfide and a specific organosilicon compound in a specific proportion in a polar organic solvent and further adding and reacting an anhydrous sulfide therewith. SOLUTION: Elementary sulfur and a part of all of an anhydrous sulfide represented by the formula MeS [Me is an alkali (alkaline earth) metal, zinc or ammonium] are dissolved or suspended in a polar organic solvent at (1:0.2) to (1:0.9) molar ratio and an organosilicon compound represented by formula I [Z is a group represented by formula II (R1 is a 1-5C alkyl, a 5-8C cycloalkyl, benzyl or phenyl; R is a 1-5C alkoxy, a 5-8C cycloalkoxy, phenoxy or benzyloxy); Alk is a 1-10C bivalent saturated hydrocarbon or a group represented by formula III; Hal is Cl or Br] and the resultant solution or suspension is then reacted with the compound represented by the formula I so as to provide (1.2:1) to (2:1) molar ratio of the compound represented by the formula I to S. A compound represented by the formula; Me2 S in an amount so that the sulfide and the total amount of the elementary sulfur are nearly equimolar is added thereto. The resultant product is subsequently isolated to provide a high-purity organosilicon disulfane represented by formula IV.
