Abstract
The first example of dimeric Mn(III)-tetraarylporphyrins able to catal yze olefin epoxidation is reported. In the presence of one equivalent of lipophilic bidentate ligand 3 the efficiency of some of these catal ysts is among the highest reported to now in 30% H2O2-promoted epoxida tion (up to 1500 overall catalytic cycles). Slightly better results we re obtained replacing 3 with two equivalents of N-hexylimidazole 10.
