2-Substituted phenylacetonitriles 1 react with 1,1-dihalo-2-phenylcyclopropanes 2 in the presence of concentrated aqueous sodium hydroxide solution and benzyltriethylammonium chloride (TEBA) as a catalyst (phase-transfer catalysis, PTC conditions), to afford 1,2-disubstituted cyclopropenes 3, with moderate to low yields.
在浓氢氧化钠水溶液和苄基三乙基氯化铵(TEBA)作为催化剂(相转移催化,PTC条件)的存在下,2-取代苯乙腈1与1,1-二卤代-2-苯基环丙烷2反应,以中等到较低的产率得到1,2-二取代环丙烯3。
