(stable up to 180 °C under air, as determined by thermogravimetric studies) and are highly active catalysts at room temperature (molybdenumcompounds) or above (tungstencompounds) in olefin epoxidation. In the case of cyclooctene as substrate, TOFs up to ca. 11800 h−1 are obtained. Moreover, most of the catalysts described here display a high selectivity in the epoxidation of cis- and trans-stilbene. In
