In an experiment conducted similarly to that in Example 4 except that the reactants were 0.8 g. of anhydrous cuprous bromide, 1 ml. of thiophen, 6.5 g. of butadiene and 5 ml. of hydrogen cyanide, and heating was continued for 17 hours at 100°C the conversion of butadiene to mononitriles was 48%, and 3-pentenenitrile was obtained in a yield of 82.2% and 2-methyl-3-butene-nitrile in a yield of 17.8% calculated on the butadiene converted.
