Versuchsvorschrift

A reaction is performed as described in Example 1, except that 10.3 mg (0.04 mmol) of (CH3CN)2PdCl2, 59.7 mg (0.16 mmol) of Ph4PCl, 157.6 mg (1.92 mmol) of anhydrous sodium acetate, 107.1 mg (0.95 mmol) of chlorobenzene and 136.2 mg (1.31 mmol) of styrene in 1 ml of DMF are reacted. Stirring is performed at 150° C. for 8 hours. With 95.6% conversion of Cl-benzene, a 70.4% yield of Heck products (84.9% trans-stilbene, 0.7% cis-stilbene, and 14.4% 1,1-diphenylethene) is obtained.
