We report Wolff rearrangement of α-diazoketones by in situ generated silver nanoclusters (Agn, 2-4 nm) from silver(I) oxide (Ag 2O) involving a nonclassical electron-transfer process. Our results show that Agn+/Agn0 redox couple allows the initial removal of an electron from α-diazoketone and its back-donation after chemical reaction(s). Controlled potential coulometry (CPC) of various α-diazoketones results in the realization of Wolff-rearranged carboxylic acids in excellent yields.

α-Diazoketones possess high electric dipole moments, as a consequence of the dipolar nature of the diazocarbonyl functional group. The vectorial analysis, theoretical calculations (PM3 and ab initio), and literature reports based on experimental and theor

The rhodium(II) acetate-catalyzed decompositin of α-diazocarbonyl compounds such as substituted α-diazoacetophenones, cyclic diazoketones, cyclic diazodiketones, and α-diazo-β-ketoesters in carbon disulfide gave 1,3-dioxathiole-2-thione derivatives in goo
