実験手順
234 g of 2-pyrazoline and 64 g of tetraethylammonium bromide were dissolved in 3,000 g of ethanol and electrolyzed with 2 F/mol of 2-pyrazoline at a current density of 6.8 A/dm2 and 30° C. Working up as described in Example 1 gave 18.2 g of 2-pyrazoline and 129 g of pyrazole. This corresponds to a conversion of 92%, a yield of 57% and a selectivity of 62%.
