Reaction Steps

2 ml of the stock solution described in Example 23 are added to 18 ml of DMF. 9.77 g (50 mmols) of 4-chlorobromobenzene and 4.52 g (55 mmols) of anhydrous sodium acetate are then added. The reaction mixture is then placed under ethylene in a pressure apparatus and is stirred for 6 hours at 10 bar and 130° C. 3.62 g (26.1 mmols) of 4-chlorostyrene are obtained, corresponding to a yield of 52% of theory (conversion figure 5200; Pd content 0.01 mol %).
