Synthesis and properties of alkynethiolate gold(i) complexes
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-CC-S)PPh3], [Au(3-C4H3S-CC-S)PPh3] and PPN[Au(p-CH 3-C6H4-CC-S)(C6F5)] by X-ray analysis. The electrochemically polymerizable mononuclear bis(alkynethiolate) gold(i) complex PPN[Au(3-C4H3S-CC-S) 2] is also described, including its electropolymerization and electrochemical properties. This journal is The Royal Society of Chemistry.

The 1,2,3-thiadiazole route to new vinylogue tetrathiafulvalenes
Cleavage of 1,4-dithiafulvene-substituted 1,2,3-thiadiazoles with base and dimerisation of the resulting alkyne-1-thiolate gives new tetrathiafulvalene-type vinylogue extended π-donors in a one pot reaction. The solvent-/base-system used (acetonitrile/NaH) was optimised for the synthesis of 1,3-dithiole-2-thiones via this route. Efficient synthesis of the important 4-formyl-1,3-dithiol-2-thione and its coupling to 2,6(7)-bisformyltetrathiafulvalene is presented. Preparation of a number of new 1,4-dithiafulvenes are reported.
