Aerobic Oxidations Catalyzed by Colloidal Nanogold

Tsukuda, Tatsuya, Tsunoyama, Hironori, Sakurai, Hidehiro·2011·Chemistry – An Asian Journal

Abstract

Recently, dispersions of gold nanoclusters in liquid media (colloidal nanogold) have been extensively used as quasi‐homogeneous catalysts for various aerobic oxidation reactions. This review describes recent progress in such reactions, with a focus on our comprehensive studies on gold clusters (<2 nm) stabilized by poly(N‐vinyl‐2‐pyrrolidone) and their participation in oxidation reactions of alcohols, α‐hydroxylation reactions of benzylic ketones, and homocoupling reactions of organoboronates, as well as formal Lewis acidic reactions, such as intramolecular hydroalkoxylation and hydroamination reactions of nonactivated alkenes. Mechanistic studies have shown that a partial electron transfer from the gold clusters to O 2 generates superoxide‐ or peroxide‐like species and Lewis acidic centers, both of which play essential roles in the catalytic reactions.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
