Application

Chloro[1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene]copper(I) is designed to serve as a versatile catalyst in a variety of chemical transformations. It facilitates the reduction of olefins and carbonyl compounds, enhances carbene transfer reactions, and acts as an efficient catalyst in the aziridination of olefins and methyleneation of aldehydes. This compound proves to be a mild yet superior catalytic agent, surpassing CuCl specifically in the methylenetriphenylphosphorane methyleneation of aldehydes and ketones. Additionally, it catalyzes the alkylation of aryl and alkenylsilanes, catalyzes the formal methylative and hydrogenative carboxylation of alkynes with carbon dioxide, and assists in the regioselective carboxylation of allylboronates with CO₂. The compound is also active in the carboxylation of organoboronic esters with potassium methyl carbonate, supports anti-Markovnikov hydrobromination of alkynes, and enables borylative cross-coupling of allenes and imines.
