摘要：

The two-phase epoxidation of olefins with sodium hypochlorite catalyzed by the salen-type Mn(III) complex 1 was examined in the presence of various additional ligands and 4-dodecyloxypyridine 1-oxide (3) was found as the most effective one. The system 1-3 was studied by conductometry and UV-Vis spectra. The results support the hypothesis that the disproportionation of the dimeric mu-oxo Mn(IV) complex producing an active oxidant is strongly favoured by the presence of 3.
