• 2-(1,4-Dioxo-1,4-dihydro-2-naphthyl)-2-methylpropanoic acid 

  Dempster-Rivett, Kieran J.; Main, Lyndsay; Nicholson, Brian K.; Denny, William A. (Blackwell Munksgaard, 2007)

  The sterically crowded title compound, C₁₄H₁₂O₄, crystallizes as centrosymmetric hydrogen-bonded dimers involving the carboxyl groups. The naphthoquinone ring system is folded by 11.5 (1)° about a vector joining the 1,4-C ...

  

• 2-Ferrocenyl-substituted pyrylium ions from coupling of ethynylferrocene with cyclomanganated chalcones 

  Prasad, Narendra Jai; Main, Lyndsay; Nicholson, Brian K.; McAdam, C. John (Elsevier, 2010)

  2-Ferrocenyl-substituted pyrylium salts are produced when orthomanganated chalcones are reacted with ethynylferrocene in CCl4. When the reaction is carried out in benzene, intermediate ferrocenyl-substituted (η5-pyranyl)Mn(CO)3 ...

• (6-Acetoxy-2-acetylphenyl-κ²C¹,O¹)tetracarbonylmanganese(I) 

  Fester, Victor D.; Main, Lyndsay; Nicholson, Brian K. (Wiley-Blackwell, 2007-10)

  The title compound, [Mn(C₁₀H₉O₃)(CO)₄], is formed by orthomanganation of 3'-acetoxyacetophenone at the sterically crowded ortho site. The atoms of the benzene and the cyclometallated rings are coplanar to within <0.018 Å, ...

  

• Alkynyl and poly-ynyl derivatives of carbon-tricobalt clusters 

  Antonova, Alla B.; Bruce, Michael I.; Humphrey, Paul A.; Gaudio, Maryka; Nicholson, Brian K.; Scoleri, Nancy; Skelton, Brian W.; White, Allan H.; Zaitseva, Natasha N. (Elsevier S.A., 2006-04-01)

  A series of alkynyl-tricobalt carbonyl clusters, Co₃(μ₃-CnR)(μ-dppm)(CO)₇ [R = But, Ph, C₆H₄I, C₆H₄C≡CPh, SiMe₃, Fc, Au(PPh₃)] containing three, five or seven carbons in the chain, have been prepared by elimination of ...

  

• Anionic germanium polycobalt carbonyl clusters. Part 2. Preparation and structure of [Net₄][Ge{Co₅(CO)₁₆}], a cluster which contains five-co-ordinate germanium 

  Croft, Rex A.; Duffy, D. Neil; Nicholson, Brian K. (1982)

  Addition of [Co(CO)₄]⁻ to [Ge{Co₄(CO)n}](n= 16, 14, or 13) under mild conditions gives good yields of [Ge{Co₅(CO)₁₆}]⁻. This forms crystals with Net₄⁺ which are orthorhombic, space group Pn2₁ a with a= 12.014(1), b= ...

• Preparation and reactions of some organic derivatives of manganese carbonyl compounds 

  Cooney, Janine M. (The University of Waikato, 1994)

  New orthomanganated aryl ketones of type 1 (Figure 1) have been prepared, including some in which the donor ketone carbonyl group is incorporated into a fused ring. Analogous derivatives of benzoates and heteroaromatic ...

  

• Gold(I) complexes and co oxidation catalysts 

  Mathieson, Trevor J. (The University of Waikato, 1998)

  Isonitrile gold(I) nitrates, (RNC)AuNO₃ (R = Buᵗ, Et or Xy) have been prepared and fully characterised. These join the rare set of gold(I) species exhibiting ligation to oxygen and are the first examples of gold(I) bonded ...

  

• Some metallacyclic complexes of the late transition metals 

  Oliver, Allen G. (The University of Waikato, 1999)

  The principal aim of this thesis is the synthesis and characterisation of four-membered metallacyclic complexes. Reactions of square-planar palladium(II), platinum(II) and gold(III) dihalide complexes with a variety of ...

  

• Electrospray-friendly ligands for the mass spectral analysis of transition-metal complexes 

  Decker, Corry (The University of Waikato, 2002)

  The key aim of this project was to develop the concept of electrospray-friendly ligands as a new ionisation method for the analysis of neutral metal complexes by electrospray mass spectrometry (ESMS). This involved introducing ...

  

• Calcium phosphate precipitation from whey permeate 

  Panova, Natalia N. (The University of Waikato, 2001)

  Currently the New Zealand Dairy Industry manufactures a very successful milk calcium product known as ALAMINTM by the precipitation of calcium phosphates (CaP) from various heated whey permeate streams. The main scientific ...
