Abstract

A series of alkynethiolate gold(I) derivatives have been synthesised by the cleavage of 4-monosubstituted 1,2,3-thiadiazoles in the presence of strong bases. The syntheses of the 1,2,3-thiadiazoles with p-cyanophenyl, p-tolyl, 2-thienyl, 3-thienyl and 9,9-dimethylfluoren-2-yl fragments are also described. All the complexes have been characterised by spectroscopic techniques and the complexes [Au(p-CH3–C6H4–C[triple bond, length as m-dash]C–S)PPh3], [Au(3-C4H3S–C[triple bond, length as m-dash]C–S)PPh3] and PPN[Au(p-CH3–C6H4–C[triple bond, length as m-dash]C–S)(C6F5)] by X-ray analysis. The electrochemically polymerizable mononuclear bis(alkynethiolate) gold(I) complex PPN[Au(3-C4H3S–C[triple bond, length as m-dash]C–S)2] is also described, including its electropolymerization and electrochemical properties.
