Modulation of the catalytic activity of manganese(iii) salen complexes in the epoxidation of styrene: influence of the oxygen source

Several achiral Mn(III) salen complexes with different groups in the diimine bridge and in the aldehyde fragment were synthesised and their catalytic activity in the epoxidation of styrene was studied at room temperature, using two oxygen sources, NaOCl or PhIO, and in two solvents, CH3CN and CH2Cl2.
