Abstract

Abstract A 1H and 13C NMR study of (phenylethynyl) (triphenylphosphine) gold(I) is presented. Contrary to the solid state findings, the existence of Au … Au contacts in solution can be excluded on the basis of experimental results. The 13C chemical shifts of various Au, Ag and Cu triphenylphosphine complexes and the corresponding SCS values are considered to rationalize the electronic behaviour of the ligand on complexation.
