Description |
1574-1578
Three mononuclear manganese(II) complexes having two N<sub>2</sub>O coordination spheres have been examined as catalysts for epoxidation of (<i>E</i>)-stilbene and styrene using PhIO and NaOCl as terminal oxidants in four different solvents. The catalytic efficiency of the complexes are observed to be influenced not only by their own structural features but also by the nature of terminal oxidant, substrate as well as the solvents. Epoxidation proceeds with the formation of two different intermediates, O=Mn(IV)(L)(X) and Cl-O-Mn(II)(L)(X) [X=NO<sub>3</sub>/SCN/N(CN)<sub>2</sub>], in presence of PhIO and NaOCl respectively. Amongst the solvents, acetonitrile is found to be the most suitable. |
