Reaction Steps

A solution containing 10 g of nitrobenzene, 1.27 g of tetramethylammonium hydroxide dihydrate and 1 g of benzonitrile was stirred at 60° C. with nitrogen bubbled into the solution via a syringe needle for 1 hour. Analysis of a sample of the reaction product by HPLC revealed N-(4-nitrophenyl)-benzamide was produced in 45% yield and azoxybenzene was generated in 22% yield based on tetramethylammonium hydroxide.
