The procedure described in Example 1 is repeated, except that 21.94 g (0.1 mol) of 3-bromobenzoyl chloride, 6.63 g (0.125 mol) of acrylonitrile, 35.37 g (0.1 mol) of tris-(2-ethylhexyl)-amine and 0.3046 g (0.001 mol) of bis-acetylacetonato)-palladium(II) in 50 ml of propionitrile are used. After a reaction time of 3 hours at 100° C., 2.05 g (0.0099 mol) of 3-bromocinnamonitrile are obtained, corresponding to a yield of 9.9% of theory; melting point 62° C. Analysis for C9H6NBr (molecular weight 208): calculated C 51.96%, H 2.91%, N 6.73%; found C 52.29%, H 2.95%, N 6.91%.
