✦ Synopsis

The first example of dimeric Mn(IlI)-tetraarylporphyrins able to catalyze olefin epoxidation is reported. In the presence of one equivalent of lipophilic bidentate ligand 3 the efficiency of some of these catalysts is among the highest reported to now in 30% H&-promoted epoxidation (up to 1500 overall catalytic cycles). Slightly better results were obtained replacing 3 with two equivalents of N-hexylimidazole 10.

## Abstract A novel cyclopentadienyl ligand bearing a chiral oxazoline pendant group (Cp^ox^) has been prepared. Its coordination to molybdenum and tungsten afforded optically pure (__R__)‐Cp^ox^M(Ξ·^3^‐C~3~H~5~)(CO)~2~ (M = Mo, W) in which the pendant oxazoline fragment is not coordinated to the me
