Abstract

The cyclisation of alkynyl alcohols and carboxylic acids in the presence of a [Cu(NHC)₂]X complex is reported. The reactions were carried out in technical grade toluene in the presence of air with a catalyst that is readily accessible. N-Heterocyclic carbenes are recognised for stabilising metal centres in a range of oxidation states, and this work further supports that NHCs can also be used as activation sites in air and moisture stable yet active catalysts.
