2-Acetothienone과 chloral을 축합시켜 chloral-2-acetothienone을 생성하였으며 이것을 탈수하여 trichloroethylidene-2-acetohienone을 합성하였다. Trichloroethylidene-2-acetothienone과 phenylhydrazine 또는 치환된 phenylhydrazine들과의 반응으로 2-aryl-6-(2-thienyl)-3(2H)-pyridazinone들을 얻었으며 hydrazine과의 반응에서는 3-(2-thienyl)-5-trichloromethyl-2-pyrazoline이 합성되었다.

Chloral-2-acetothienone was synthesized from the condensation of 2-acetothienone with chloral, and trichloroethylidene-2-acetothienone was obtained from the dehydration of chloral-2-acetothienone. From the reaction of trichloroethylidene-2-acetothienone with phenylhydrazine or substituted phenylhydrazines 2-aryl-6-(2-thienyl)-3(2H)-pyridazinones were obtained. 3-(2-Thienyl)-5-trichloromethyl-2-pyrazoline was synthesized from the reaction of trichloroethylidene-2-acetothienone with hydrazine hydrate.
