DOI: 10.1021/acs.orglett.1c04099
Abstract: An efficient synthetic route for the construction of N2-aryl 1,2,3-triazoles is reported via sequential C-N bond formation and electro-oxidative N-N coupling under metal-free conditions. Readily accessible 2-aminoacrylates and aryldiazonium salts were used as starting materials,… read more here.
