Treatment of aldehydes and ethyl 2-phenylsulfinylacetate (1)in the presence of piperidine gives Z-isomers (Z-2) of 2-phenylsulfinyl-2-alkylideneacetates (2). Thermolysis of Z-2 results in the formation of ethyl E,E-2,4-dienoates (3).
醛类和乙基2-苯基亚磺酸乙酸酯(1)在哌啶存在下处理,生成2-苯基亚磺酸-2-烯基乙酸酯(Z-2)的Z-异构体。Z-2的热分解产生乙基E,E-2,4-二烯酸酯(3)。
