Abstract

Manganese-complexes of a new series of tetraarylporphyrins, featuring bothchlorine atoms in ortho, ortho' positions and N-mono- or N,N-disubstitutedsulphonamido groups in meta on the meso-phenyls, were used as catalysts inthe epoxidation of alpha-olefines in the presence of diluted (17.5%) H2O2 as primary oxidant. The catalytic efficiency of these catalysts is related to the polarity of the chains and the N, N-dialkylsulphonamido porphyrins turned out to be more reactive than the robust Mn-TDClPP in the epoxidationsof styrenes.
