With tetrabutyl-ammonium chloride; potassium hydroxide; at 23℃; | To synthesize bis(4-vinylthiophenyl)sulfide, 4,4?- thiobis(benzenethiol) was first reacted with an excess of 1 ,2-dichloroethane in the presence of KOH and tetrabutylammonium chloride at room temperature (23 C.). The bis[4-(2-chloroethylthiophenyl)sulfide obtained was dehydrohalogenated with KOH in water at 85 C. to form bis(4-vinylthiophenyl)sulfide. Bis(4-vinylthiophenyl)sulfide was obtained as a colourless, low-viscosity liquid at room temperature, with a viscosity of only 17 mPa s (23 C.). The refractive index n is 1.695 and the polymerization shrinkage AV is -7.8 vol.-%. The polymerization shrinkage was measured in accordance with DIN 13907: ?Dentistry:Polymerization shrinkage of filling materials?. |
