The ammoximation of cyclohexanone using preformed hydrogen peroxide (H 2 O 2 ) is currently applied commercially to produce cyclohexanone oxime, an important feedstock in nylon-6 production. We demonstrate that by using supported gold-palladium (AuPd

The oxidative coupling of benzoic acids with alkynes and alkenes effectively proceeds in the presence of a Rh catalyst and an appropriate oxidant to produce the corresponding isocoumarin and phthalide derivatives, respectively. Interestingly, by usin
