Trideuteromethylation of Alkyl and Aryl Bromides by Nickel-Catalyzed Electrochemical Reductive Cross-Electrophile Coupling

Abstract A new nickel-catalyzed electrochemical, reductive cross-coupling for the trideuteromethylation of alkyl and aryl bromides is reported in which CD3 arenesulfonate derivatives were used as effective and readily available CD3 sources. The CD3-labeled products were obtained with good yields. It was demonstrated that this methodology is scalable and can be efficiently used for various methylations, including 13CH3 and 13CD3 labeling.
