| Product | 2-Methylstilbene | HCID 606655 | 55.6% |
Reaction Steps
The procedure described in Example 1 is followed, except that 15.5 g (0.1 mol) of o-toluic acid chloride, 13 g (0.125 mol) of styrene, 23.2 g (0.125 mol) of tri-n-butylamine and 0.225 g (0.001 mol) of palladium acetate are used. After a reaction time of 4 hours at 120° C., in 100 ml of cyclohexanone as the solvent, 10.8 g (0.0556 mol) of 2-methylstilbene, corresponding to a yield of 55.6% of theory, are obtained; melting point 92°-93° C.
