Abstract
In the presence of imidazole, Mn-(or Fe-) porphyrins catalyse the epoxidation of various alkenes including alk-1-enes by H2O2; with chloromanganese(tetra-2,6-dichlorophenylporphyrin) as a catalyst, alkene conversion by a few equivalents of H2O2 is complete within less than 1 h at 20 °C and epoxide yields are very high (90–99%).Keywords
