High molecular weight, freestanding films of poly(2,5-furylene vinylene) (PFV) are readily prepared via a water soluble precursor polymer, are electrochemically reversibly donor and acceptor dopable, and reach conductivities as high as 36 S/cm on acceptor doping.

Furfural is recognised as an attractive platform molecule for the production of solvents, plastics, resins and fuel additives. Furfurylamines have many applications as monomers in biopolymer synthesis and for the preparation of pharmacologically active compounds, although preparation via traditional synthetic routes is not straightforward due to by-product formation and sensitivity of the furan ring to reductive conditions. In this work transaminases (TAms) have been investigated as a mild sustainable method for the amination of furfural and derivatives to access furfurylamines. Preliminary screening with a recently reported colorimetric assay highlighted that a range of furfurals were readily accepted by several transaminases and the use of different amine donors was then investigated. Multistep synthetic routes were required to synthesise furfurylamine derivatives for use as analytical standards, highlighting the benefits of using a one step biocatalytic route. To demonstrate the potential of using TAms for the production of furfurals, the amination of selected compounds was then investigated on a preparative scale.
Studies on Organolanthanide Complexes. Part 55. Synthesis of Furan-bridged Bis(cyclopentadienyl) Lanthanide and Yttrium Chlorides, and Ligand and Metal Tunnig of Reactivity of Organolanthanide Hydrides (in situ)

Four new complexes (Ln = Y, Yb, Sm or Nd) were synthesised by using furan-bridged bis(cyclopentadienes) as ancillary ligands and characterized by elemental analyses, mass, IR and 1H NMR spectroscopy.The spectra indicate that these complexes are chloride-bridged dimers and the two furan-bridged cyclopentadienyl rings co-ordinate to each metal in a chelating fashion with intramolecular co-ordination between the oxygen atom and the metal.The effects of the bridging chain and the central metal upon the reactivity of organolanthanide hydrides generated in situ form the -NaH system were investigated.The reactivity can be tuned not only by varying the ligands but also by taking advantage of the lanthanide contraction.The ligand tunability varies for different reactions.More reactive organolanthanide hydride species (in situ) can be obtained by both 'ligand tuning' and 'metal tuning', i.e. by selecting the appropriate ancillary ligands and the early lanthanide metals.
