Reaktionsschritte
The procedure described in Example 47 is repeated, but using 7.07 g (25 mmols) of 4-bromoiodobenzene and 1.83 g (27.5 mmols) of acrylonitrile. After a reaction time of 8 hours at 130° C., 3.95 g (19.0 mmols) of 4-bromocinnamonitrile are obtained, corresponding to a yield of 76% of theory (conversion figure 7600; Pd content 0.01 mol %).
