Se powder as the selenating reagent, the copper-catalyzed double C–Se cross-coupling of aryl iodides, epoxides, and elemental selenium has been developed. This strategy provides a straightforward approach to the synthesis of β-hydroxy phenylselenides with excellent regioselectivity of the ring opening reaction. This process proceeds in generally good yields and is compatible with a broad range of functional

With the supported “clayniac” catalyst, in the presence of i-butyraldehyde as a sacrificial reducer, olefins are epoxidized in good yields by compressed air at roomtemperature, in a convenient procedure.

We report here a flexible synthesis of chiral, D4-symmetric porphyrins from cyclic ketone starting materials. Two porphyrins have been synthesized from the terpene 1-R-(+)-nopinone, obviating the need to perform a resolution. The chloromanganese derivative of one of these porphyrins is a good catalyst for the epoxidation of terminal alkenes, providing epoxides with e.e.'s of 70% with high turnover
