2-substituted indazoles from electrogenerated ortho-nitrosobenzylamines

Article abstract of DOI:10.1016/S0040-4020(98)00058-1

An electrochemical methodology for an efficient access to ortho- nitrosobenzylamines has been developed. These products cyclize intramolecularly producing the desired 2-substituted indazoles in high yields. The electrochemical procedure overcomes limitations of previous chemical methods.
