A multinuclear 1H, 13C and 11B solid-state MAS NMR study of 16- and 18-electron organometallic ruthenium and osmium carborane complexes

Barry, Nicolas P.E., Kemp, T.F., Sadler, P.J., Hanna, J.V. 20 February 2014 (has links)
Yes / The first 1H, 13C, 31P and 11B solid state MAS NMR studies of electron- deficient carborane-containing ruthenium and osmium complexes [Ru/Os(p-cym)(1,2-dicarba-closo-dodecaborane-1,2- dithiolate)] are reported. The MAS NMR data from these 16-electron complexes are compared to those of free carborane-ligand and an 18-electron triphenylphosphine ruthenium adduct, and reveal clear spectral differences between 16- and 18-electron organometallic carborane systems in the solid state. / We thank the Swiss National Science Foundation (grant no. PA00P2-145308 to NPEB), the ERC (grant no. 247450 to PJS), EPSRC (grant no. EP/F034210/1) and EC COST Action CM1105 for support. JVH thanks EPSRC and the University of Warwick for partial funding of the solid state NMR infrastructure at Warwick, and acknowledges additional support obtained through Birmingham Science City: Innovative Uses for Advanced Materials in the Modern World (West Midlands Centre for Advanced Materials Project 2), with support from Advantage West Midlands (AWM) and partial funding by the European Regional Development Fund (ERDF).

The Preparation of Aryl-Carboranes and Re-Metallocarboranes as Anti-Estrogens

Chankalal, Raymond 02 1900 (has links)
<p> The estrogen receptor (ER) plays an integral role in the proliferation of hormone dependent breast cancer. Recently a number of organometallic compounds and closocarboranes, which demonstrate affinity for the estrogen receptor, were prepared as novel types of anti-estrogens. This thesis describes the synthesis and characterization of a new class ofinorganic anti-estrogens derived from Re-metallocarboranes. </p> <p> Chapter 2 describes the first series of targets which include three monoarylated Re-metallocarboranes. Two different synthetic routes were used to complex the [Re(C0)3t core to carborane ligands, one of which involves microwave irradiation of a one pot mixture that produces the desired complexes in almost complete conversion ratios. One compound, 2.10, contains a single phenol substituents, which is predicted to show ER binding affinity based on previous reports ofthe closo-carborane analogue. </p> <p> Chapter 3 describes the synthesis and characterization of diarylated Remetallocarboranes. Two of the compounds, 3.7 and 3.8, are expected to show high binding affinity for the ER because they are inorganic analogues of the well known antiestrogen Tamoxifen. </p> / Thesis / Master of Science (MSc)
