Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 29046-78-4, is researched, Molecular C4H10Cl2NiO2, about Generation and Oxidative Reactivity of a Ni(II) Superoxo Complex via Ligand-Based Redox Non-Innocence, the main research direction is hydrazono tolyl pyrrolo nickel complex preparation crystal mol structure; superoxo nickel hydrazono tolyl pyrrolo preparation oxidation alc hydrocarbon.Application of 29046-78-4.
Metal ligand cooperativity is a powerful strategy in transition metal chem. This type of mechanism for the activation of O2 is best exemplified by heme centers in biol. systems. While aerobic oxidations with Fe and Cu are well precedented, Ni-based oxidations are frequently less common due to less-accessible metal-based redox couples. Some Ni enzymes use special ligand environments for tuning the Ni(II)/(III) redox couple such as strongly donating thiolates in Ni superoxide dismutase. A recently characterized example of a Ni-containing protein, however, suggests an alternative strategy for mediating redox chem. with Ni by using ligand-based reducing equivalent to enable O binding. While this mechanism has little synthetic precedent, the authors show here that Ni complexes of the redox-active ligand tBu,TolDHP (tBu,TolDHP = 2,5-bis((2-t-butylhydrazono)(p-tolyl)methyl)-pyrrole) activate O2 to generate a Ni(II) superoxo complex via ligand-based electron transfer. This superoxo complex is competent for stoichiometric oxidation chem. with alcs. and hydrocarbons. Coupling ligand-based redox chem. with functionally redox-inactive Ni centers enables oxidative transformations more commonly mediated by metals such as Fe and Cu.
