This is an exciting time in the development of our understanding of the nature and mode of action of the catalytic centres of the oxomolybdoenzymes and their close relatives the tungsten enzymes. Crystal structures of representatives of these two families of enzymes are now available and include the molybdoenzymes dimethyl sulfoxide reductase from Rhodobacter capsulatus and R. sphaeroides, aldehyde...
Several poly(p-aniline) leucoemeraldine base oligomers were characterised by 13 C NMR spectroscopy. The uncapped trimer and tetramer were obtained by a new method involving a coupling step with copper as a catalyst in DMF. The phenylcapped tetramer, hexamer and octamer were obtained via the “modified Honzl route”.The leucoemeraldine base phenylcapped tetramer has been oxidised to its emeraldine...
