Reaction Steps

One (1) part of benzo[b]thiophen-3(2H)-one and 0.5 parts of malononitrile were dissolved in ethanol, and 0.8 parts of diazobicycloundecene was added dropwise to the solution for 10-hour reaction at room temperature. After the completion of the reaction, ethyl acetate and water were added to the reaction product to separate it into phases, the organic phase of which was concentrated to solid, thereby obtaining 0.7 parts of 3-dicyanoethylidenebenzo[b]thiophene (in a yield of 54%).
