Vorschrift

Under argon, a solution containing 218 mg of p-nitrobromobenzene, 141 mg of styrene, 0.3 ml of triethylamine, and 1 ml of propylene carbonate stabilized colloid solution with a palladium content of 4.023 mg is heated at 130° C. with stirring in a sealed vessel for 4.5 h. At the end of the reaction, 2 ml of diethyl ether/dichloromethane (1:1) is added, and the mixture is filtered. The yield of desired product as determined by GC is 96%.
