Control over borrowing hydrogen and acceptorless dehydrogenative coupling process for the Co(iii)–NHC catalysed chemoselective alkylation and cyclisation of 1,2-phenylenediamine with alcohols

Abstract

Chemoselective alkylation and cyclisation of 1,2-phenylenediamine with alcohols via control of cobalt–NHC catalysed borrowing hydrogen and acceptorless dehydrogenative coupling is achieved by tuning the triazole substituent of NHC ligand system.
