A well-defined, bench-stable nickel catalyst is presented here, that can facilitate double alkylation of a methyl ketone to realize wide variety cycloalkanes. The performance the depends on ligand redox process comprising an azo-hydrazo couple. source bis electrophile in this 1,n-diol, so (n+1)-membered cycloalkanes be furnished stereoselective manner. reaction follows cascade dehydrogenation/hydrogenation reactions and adopts borrowing hydrogen (BH) method. thorough mechanistic analysis including interception key radical intermediates DFT calculations supports radical-mediated dehydrogenation hydrogenation reactions, which quite rare BH chemistry. In particular, radical-promoted distinctly different from conventional hydrogenations involving metal hydride complementary ubiquitous two-electron driven reactions.
