| Product | 4-[(E)-2-Phenylethenyl]benzonitrile | HCID 609608 | 26.8% |
Reaction Steps
The procedure described in Example 1 is followed, except that 16.55 g (0.1 mol) of 4-cyanobenzoyl chloride, 13.02 g (0.125 mol) of styrene, 35.37 g (0.1 mol) of tri-n-octylamine, 50 ml of ethyl butyrate as the solvent and 0.0575 g (0.0001 mol) of bis-(dibenzylideneacetone)-palladium(O) are used. After a reaction time of 2 hours at 100° C., 5.5 g (0.0268 mol) of 4-cyanostilbene, corresponding to a yield of 26.8% of theory, are obtained; melting point 119° C.
