TL;DR: In this article, the performance of Co(II)-Schiff base complexes toward selective oxygenation of organic molecules related to biological systems has been reviewed, and preliminary kinetic studies on the regioselective peroxyquinolato Co(III) complex formation show that the reaction involves a rate-determining hydrogen abstraction from the phenol substrate by a superoxo Co(3) complex initially formed, followed by rapid reduction of the resulting phenoxy radical with Co(2) species leading to the formation of a phenolato co-type complex, to which

TL;DR: In this paper, a unique mechanism for a cobalt-Schiff base complex-catalyzed monooxygenation of alkenes is reported, which involves rate-determining decomposition of a benzyl alcoholatocobalt(III) complex to benzaldehyde and a hydridocobalcoobalt species, followed by rapid addition of the hydride intermediate to styrene, and dioxygen incorporation into the resulting organobalt complex.

TL;DR: In this paper, a competition reaction between 2,6-di-t-butylphenol (I) and a singlet oxygen acceptor (linalool), quenching by a quencher (β-carotene), and the effect of concentrations of I were examined.

TL;DR: In this article, a mechanism involving electron transfer from the substrate to cobalt(III) species is suggested, which leads to a high yield of secondary aromatic amines in high yield.

TL;DR: The peroxy-p-quinolatocobalt(III) complex as mentioned in this paper is a cobalt-II Schiff-base complex, which is derived from 4-alkyl-2,6-di-t-butyl phenols.
