Glaser–Hay hetero-coupling in a bimetallic regime: a Ni(ii )/Ag(i ) assisted base, ligand and additive free route to selective unsymmetrical 1,3-diynes
Abstract
A Ni(OAc)2/Ag(OTf) catalysed coupling of aryl alkynes and propargylic alcohol/ether/ester gave the corresponding unsymmetrical 1,3-diynes in good to excellent yields. The reaction does not require bases, ligands or additives and shows excellent hetero-selectivity, thereby addressing the current challenges in the field of coupling of two different terminal...
