Chromium silicalite-2 (CrS-2): an efficient catalyst for the direct oxidation of primary amines to nitro compounds with TBHP
Abstract
A chromium-containing medium-pore molecular sieve (Si:Cr > 140:1) having MEL (CrS-2) topology efficiently catalyses the direct oxidation of various primary amines to the corresponding nitro compounds using 70%tert-butyl hydroperoxide (TBHP) as the oxidant.
