反応手順
A reaction is performed as described in Example 1, except that 3.9 mg (0.015 mmol) of (CH3CN)2PdCl2, 34.9 mg (0.09 mmol) of Ph4PCl, 520.9 mg (6.35 mmol) of anhydrous sodium acetate, 499.6 mg (3.118 mmol) of Br-benzene and 489.3 mg (4.7 mmol) of styrene are reacted in 1.5 ml of DMF. Stirring is performed at 130° C. for 5 hours. According to the processing described in Example 1, a 74.8% yield of Heck products (85.0% trans-stilbene, 0.5% cis-stilbene, and 14.5% 1,1-diphenylethene) is obtained with 74.6% conversion of Br-benzene.
