The halohydroxylation of 1-cyclopropylallenes would generate two multisubstituted C=C double bonds and at the same time stereoselectively gives 5-halohexa-3,5-dien-1-ols in moderate to good yields. The latter could be transformed into the corresponding alkynyl-substituted conjugated dienes through the further Sonogashira coupling.
1-环丙基丙烯的卤代羟基化反应将产生两个多取代的C = C双键,同时立体选择性地以中等至良好的收率生成5-卤代六-3,5-二烯-1-醇。后者可以通过进一步的Sonogashira偶联转化为相应的炔基取代的共轭二烯。
