The reaction of Fe(NCS)3 prepared in situ in MeOH with Hqsal-X (Hqsal-X = 5-X-N-quinolylsalicylaldimine) in CH2Cl2 yields the FeIII complexes, [Fe(qsal-X)2]NCS·solvent (X = F 1; X = Cl, 2, Br, 3 solvent = MeOH; X = I, solvent = 0.25CH2Cl2·0.5MeOH 4) in moderate to good yields. IR spectroscopy ...

The synthesis of donor- (D) and/or acceptor (A)-expanded radialenes has been developed on the basis of readily available dibromoolefin (7), tetraethynylethene (10 and 20), and vinyl triflate (12) building blocks. The successful formation of D/A radialenes relies especially on (1) effective use ...
14-10-2014 | James I. Murray; Rudiger Woscholski; Alan C. Spivey, Chemical Communication, 2014
The chemoselective phosphorylation of hydroxyl containing amino acid derivatives and polyols by phosphoryl chlorides catalyzed by 2-aryl-4-(dimethylamino)pyridine-N-oxides is described.
14-10-2014 | Simon Williams; Jessica King; Maria Revell; Merilyn Manley-Harris; Megan Balks; Franziska Janusch; Michael Kiefer; M ..., Journal of Agricultural and Food Chemistry, 2014
A method was designed and validated for the analysis of dihydroxyacetone in the floral nectar of ma̅nuka (Leptospermum scoparium). The method was applied to samples collected from different regions of the North Island and the Nelson region of the upper South Island of New Zealand during the ...

An ion mobility mass spectrometer has been modified to allow optical interrogation of ions with different mass-to-charge (m/z) ratios and/or mobilities (K). An ion trapping procedure has been developed which allows us to store ions for several seconds enabling UV photodissociation (UVPD).

We study charge injection and transport in PbSe nanocrystal thin films. By engineering the contact metallurgy and nanocrystal ligand exchange chemistry and surface passivation, we demonstrate partial Fermi-level pinning at the metal–nanocrystal interface and an insulator-to-metal transition with ...

Laboratory measurements of vapour pressures for atmospherically relevant compounds were collated and used to assess the accuracy of vapour pressure estimates generated by seven estimation methods and impacts on predicted secondary organic aerosol. Of the vapour pressure estimation methods that ...

The photochemistry of methylamine has been investigated following state-specific excitation of the S1 state. 2 + 1 resonance-enhanced multiphoton ionization was used to detect nascent methyl radical products via the 3p2A2″–X̃2A2″ electronic transition. Methyl radicals were formed at all ...
07-10-2014 | Maheswaran Shanmugam; Naushad Ahmed; Chinmoy Das; Shefali Vaidya; Anant Kumar Srivastava; Stuart Langley; Keith S. M ..., Dalton Transactions, 2014
We have established the coordination potential of the Schiff base ligand (2-methoxy-6-[(E)-2’-hydroxymethyl-phenyliminomethyl]-phenolate (H2L)) via the isolation of various M(II)-Ln(III) complexes (where M(II) = Ni or Zn and Ln(III) = La or Pr or Gd). Single crystals of these five complexes were ...
