Claims
- 1. A process for the preparation of styrene and stilbene compounds which comprises reacting at a temperature of about 25.degree. to 150.degree. C. and a pressure of about 1 to 100 atmospheres an aryl sulfonyl chloride of the formula ArSO.sub.2 Cl, wherein Ar represents a moiety derived from benzene or toluene, with an olefinic compound of the formula R-CH.dbd.CH.sub.2, wherein R represents H, an alkyl group having up to about 12 carbon atoms, or a substituted or unsubstituted phenyl group, in the presence of a base having a pKa greater than that of pyridine and a catalyst consisting essentially of palladium in a concentration of about 0.1 to 10 mole percent based on the concentration of said aryl sulfonyl chloride.
- 2. The process of claim 1 wherein the reaction temperature is about 50.degree. to 100.degree. C.
- 3. The process of claim 1 wherein said base comprises triethylamine, sodium carbonate, or potassium carbonate.
- 4. The process of claim 1 wherein the reaction system further comprises an inert solvent.
- 5. The process of claim 4 wherein said inert solvent comprises tetrahydrofuran, acetonitrile, methylene chloride, or diethyl ether.
- 6. The process of claim 5 wherein said Ar represents toluene.
- 7. The process of claim 6 wherien said aryl sulfonyl chloride is p-toluenesulfonyl chloride.
- 8. The process of claim 7 wherein said compounds of the formula Ar-Ch.dbd.CH-R is 4,4'-dimethylstilbene.
- 9. A process for the preparation of styrene compounds which comprises reacting at a temperature of about 25.degree. to 150.degree. C. and a pressure of about 1 to 100 atmospheres an aryl sulfonyl chloride of the formula ArSO.sub.2 Cl, wherein Ar represents a moiety derived from benzene, with an olefinic compound of the formula R-CH.dbd.CH.sub.2, wherein R represents H, an alkyl group having up to about 12 carbon atoms, or a substituted or unsubstituted phenyl group, in the presence of a base having a pKa greater than the of pyridine and a catalyst consisting essentially of palladium in a concentration of about 0.1 to 10 mole percent, based on the concentration of said aryl sulfonyl chloride.
