A regioselective Ru(II)-catalyzed C–H alkylation of pyridotriazoles with maleimides has been developed to access triazolopyridine–succinimide frameworks with good to an excellent yield of products.
A highly effective method for synthesizing N-arylhydrazones by means of light-promoted C–N coupling of (hetero)aryl halides with benzophenone hydrazone with catalysis by a Ni(II)–aryl halide complex was reported.
The review summarizes the use of nitrous oxide (N2O, ‘laughing gas’) as a diazo transfer reagent in synthetic chemistry.
This review focuses on recent advances in coupling reactions on various heteroaromatic rings via C–H bond functionalization, and provides a detailed, in-depth investigation into the mechanisms of most reactions of C–H functionalization on heteroaromatic rings.
Electrochemical-mediated rearrangement has emerged as one of the most important research fields in organic chemistry. This review systematically summarizes the diverse transformations and applications of electrochemistry in rearrangement reactions.
