Cross-pinacol coupling of two different carbonyl compounds was achieved through successive one-electron transfer processes under photocatalytic conditions. In the reaction, an umpoled anionic carbinol synthon generated in situ to react nucleophilically with a second electrophilic compound. It revealed that CO2 additive promoted generation suppress undesired radical dimerization. A wide variety aromatic and aliphatic substrates underwent cross-pinacol afford corresponding unsymmetric vicinal 1,2-diols, which even combination reactants similar structures such as aldehydes ketones were also well tolerated high cross-coupling selectivity.

Electrocarboxylation reaction, which employs organic electrosynthesis to achieve the utilization of CO2 as a carboxylative reagent, provides powerful and efficient tool for preparation carboxylic acid. In some electrocarboxylation reactions, also acts promoter facilitate desired reaction. This concept mainly highlights recent -promoted reactions via CO2⋅- intermediate or transiently protective carboxylation active with .
