DOI: 10.1021/acs.inorgchem.9b03767
Abstract: Heme active sites are capable of oxidizing organic substrates by four electrons using molecular oxygen (heme dioxygenases), where a dioxygen (O2) adduct of heme (FeIII-O2•-) acts as the primary oxidant, in contrast to monooxygenases, where… read more here.

DOI: 10.1021/acs.orglett.8b01762
Abstract: A facile insertion of ruthenium into aromatic C-H and allylic C-N bonds are the key steps in a [Ru( p-cymene)Cl2]2-catalyzed ortho-C-H allylation of benzoic acids. This protocol allows drawing on the large pool of allylic… read more here.
