Procedure

The procedure described in Example 26 is repeated, but using 4.63 g (25 mmols) of 4-bromobenzaldehyde and 3.16 ml (27.5 mmols) of styrene. After a reaction time of 4 hours at 130° C., 3.74 g (18.0 mmols) of 4-formylstilbene are obtained, corresponding to a yield of 72% of theory (conversion figure 7200; Pd content 0.01 mol %).
