The chemoselective oxidation of vicinal diols to α-hydroxyketones is a challenge in organic syntheses because not only does the diol need to be oxidized selectively to a monocarbonyl compound, but diols are also prone to overoxidation and oxidative cleavage. Employing a cationic palladium complex, [(neocuproine)Pd(OAc)]2(OTf)2, we were able to demonstrate the selective oxidation of glycerol to dihydroxyacetone mediated by either benzoquinone or O2 as the terminal oxidant, an accomplishment that has little precedent in homogeneous catalysis. Mechanistic studies were undertaken to uncover the nature of this remarkable chemoselectivity. Kinetic and deuterium-labeling studies implicate reversible β-hydride elimination from isomeric Pd alkoxides and turnover-limiting displacement of the dihydroxyacetone product by benzoquinone. We successfully extended this methodology to other terminal 1,2-diols and symmetric vicinal 1,2-diols and have carried out aerobic oxidation of these substrates catalyzed by 1. Examination of the reactivity of 1 with conformationally-restricted 1,2-cyclohexanediols suggests that the diol must chelate to the Pd center for effective oxidation to the hydroxyketone product. In a separate project, we have also investigated the electrocatalytic reduction of dioxygen by several dinuclear copper complexes, an important reaction for fuel cell applications.

"Cross-Coupling Reactions: An Overview opens with an overview of the fundamentals and applications of the young and fast developing area of transition metal catalyzed/mediated oxidative (dehydrogenative) C-H/C-H coupling reactions between two (hetero)arenes. Continuing, the authors highlight the recent advances regarding the ligand supported transition metal-catalyzed domino (cascade) or one-pot syntheses of various heterocycles involving cross-coupling reactions. The recent advances in Cu catalyzed tandem reactions for heterocycle synthesis are also addressed. Cu metal chemistry has garnered attention as a potential alternative to precious transition metals, being cheaper, more sustainable and more easily available. A comprehensive account of research on green chemical routes is provided, involving various palladium metal-based catalysts utilized in facilitating cross-coupling reaction in aqueous media. Reported decarboxylative cross-coupling reactions are discussed along with suitable examples, focusing on their mechanism of action"--
