Abstract

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.
