The oxidation of C-H bonds to carbonyl functional groups using molecular oxygen (O2) is a desirable process as O2 is environmentally benign and inexpensive. However, oxidations that employ O2 have lower product selectivity, making it industrially unappealing. The metal complexes NiCl(π-cinnamyl)(NHC) oxidize stoichiometrically with O2 as the oxidant to selectively form the ketone and aldehyde products.
This thesis details the attempted catalysis with the NiCl(π-allyl)(NHC) complex and the stoichiometric reactivity of NiCl(π-allyl)(NHC) and NiCl(π-cinnamyl)(NHC) complexes upon O2 exposure. An investigation of the intermediate and decomposition species of the NiCl(π-allyl)(NHC) complex was conducted. The complexes …
