The preparation of sulfur-containing organosilicon compounds

The present invention relates to a process for the production of organosilicon compounds of the formulaZ-Alk-Sn-Alk-Z(I)in which Z is selected from the group consisting of where R1 is an alkyl group of 1 to 4 carbon atoms, cyclohexyl or phenyl; R2 is alkoxy of 1 to 8 carbon atoms, or cycloalkoxy of...

More Information
Summary:The present invention relates to a process for the production of organosilicon compounds of the formulaZ-Alk-Sn-Alk-Z(I)in which Z is selected from the group consisting of where R1 is an alkyl group of 1 to 4 carbon atoms, cyclohexyl or phenyl; R2 is alkoxy of 1 to 8 carbon atoms, or cycloalkoxy of 5 to 8 carbon atoms; Alk is a divalent hydrocarbon of 1 to 18 carbon atoms and n is an integer of 2 to 8; comprising reacting (A) a compound of the formula:Z-Alk-X(II) when X is Cl or Br; with (B) an ammonium hydrosulfide or alkali metal hydrosulfide and (C) sulfur; wherein the reaction is conducted in the presence of a phase transfer catalyst and an aqueous phase.
