実験手順

After the reaction, the GC standards n-decane and n-hexadecane are added, and 3 ml of diethyl ether is added to the mixture. After filtering off the solids, the filtrate is examined by gas chromatography: With 78.5% conversion of Cl-benzene, an 80% yield of Heck products (86.5% trans-stilbene, 0.3% cis-stilbene, and 13.2% 1,1-diphenylethene) is obtained.
