Chromium Silicalite-2 (CrS-2): An Efficient Catalyst for the Chemoselective Epoxidation of Alkenes with TBHP.

Chromium-containing medium-pore molecular sieve (Si/Cr > 140) having MEL (CrS-2) topology efficiently catalyses the chemoselective epoxidation of various olefins to the corresponding epoxides using 70%tert-butyl hydroperoxide (TBHP) as an oxidant.
