Regio- and stereoselective oxidative dimerization of alkyl 3-arylpropynoates in the system CF3CO2H-CH2Cl2-PbO2 (1–30 h, 0–20°C) leads to dialkyl (E)-2,3-bis(arylcarbonyl)-2-butene-1,4-dioates with trans arrangement of the substituents at the double bond.
在CF3CO2H-CH2Cl2-PbO2体系中,烷基3-芳基丙炔酸酯的区域选择性和立体选择性氧化二聚化(1-30小时,0-20°C)生成了双烷基(E)-2,3-双(芳基羰基)-2-丁烯-1,4-二酸酯,其双键处取代基呈反式排列。
