Outline of Final Research Achievements

It was found that a Pd(II) peroxocarbonate complex bearing cavity-shaped carbene ligands, which is formed through carbon dioxide capture, undergo oxygen-atom transfer reaction toward a phosphine to afford a Pd(II) carbonate complex and the corresponding phosphine oxide. The oxygen-atom-transfer reaction was dramatically accelerated by lithium chloride, which plays a role of releasing the peroxocarbonate moiety from the Pd complex. In addition, it was shown that the peroxocarbonate complex reacts with a sulfoxide to form the Pd carbonate complex and a sulfone.
