摘要
应用苄基三乙基氯化胺作相转移催化剂,在氢氧化钠水溶液和醇中反应,分离出一种反应中间体离子对Q^+-OR(Q^+=(?)—CH_2(?)(C_2H_5)_3,R=CH_3,C_2H_5)。用实验方法证实了硝基氟苯和醇,氢氧化钠通过季铵盐相转移催化剂合成硝基苯烷醚,该反应是按照C. M. Starks提出的相转移催化机理进行的。
A kind of reaction intermediate ion pair Q^(+-)OR(Q^+=PhCH_2N^+(C_2H_5)_3, R=CH_3, C_2H_5) was separated by the use of quaternary ammonium salts as phase transfer catalysts (PTC). it was proved that the synthesis of ethers from nitrochlorobenzene, alcohol and sodium hydroxide by the use of quaternary ammonium salts as PTC. Obeys the mechanism of phase transfer catalysis proposed by C. M. Starks.
