研究了以连二亚硫酸钠作还原剂。聚烷基紫精-十二烷基硫酸根复合物(PRV-LS)作电子转移剂于杂相条件[Na2S2O4(水)-PRV-LS-PhCHBrCHBrCOOEt(二氯甲烷)催化2, 3-二溴-3-苯基丙酸乙酯的脱溴反应。结果表明: PRV-LS特别是聚丁基紫精-十二烷基硫酸根复合物(PBV-LS)具有良好的诱导PhCHBrCHBrCOOEt脱溴能力。

The debromination of ethyl 2, 3-dibromo-3-phenylpropionate (PhCHBrCHBrCOOEt) by sodium dithionite (Na2S2O4) using polyalkyl viologen-lauryl sulfate complexes (PRV-LS) as Electron-transfer catalys (ETC) was studied under heterophase condition Na2S2O4 (in H2O) -PRV-LS-PhCHBrCHBrCOOEt (in CH2Cl2)]. The results show that PRV-LS, especially polybutylviologen-lauryl sulfide complex (PBV-LS), have good abilities to induce the debromination of PhCHBrCHBrCOOEt under mild conditions.
