The pallada(IV)cyclic complex [Pd(CH2CH2CH2CH2)(mq)(bpy)]Br (6) has also been isolated. The first structural analysis of an arylpalladium(IV) complex, Pd(mq)MePh{(pz)2BH2} (8), is reported. Complex 8 occurs as two isomers and the one examined
  34. by X-ray crystallography has the fac-PdC3 configuration with the phenyl group trans to the quinoline nitrogen donor. NMR spectra of 8 indicate that the other isomer has the methyl group trans to the quinoline nitrogen donor. Similar geometric isomerism occurs for [Pd(mq)MePh(bpy)]BF4 (4). Structural studies of the dimethylpalladium(IV) complex Pd(mq)Me2{(pz)2BH2} (7) and the platinum(IV) cation in [Pt(mq)Me2(bpy)]BF4.0.75(CH2Cl2) (5) reveal
  35. similar structures. The cation [Pd(mq)Me2(bpy)]+ is less stable than the methyl(phenyl)palladium(IV) analogue (2), decomposing in (CD3)2CO by reductive elimination to form ethane and 8-ethylquinoline in ~1:2 ratio, together with the Pd(II) products [Pd(mq)(bpy)]Br and PdBrMe(bpy). A complex mixture of 8-substituted-quinolines (saturated and unsaturated substituents) were obtained as the major products of decomposition of [Pd(CH2CH2CH2CH2)(mq)(bpy)]Br (6), consistent with mq...CH2 coupling to give Pd(II) species that undergo further decomposition." name="eprints.abstract" />

The pallada(IV)cyclic complex [Pd(CH2CH2CH2CH2)(mq)(bpy)]Br (6) has also been isolated. The first structural analysis of an arylpalladium(IV) complex, Pd(mq)MePh{(pz)2BH2} (8), is reported. Complex 8 occurs as two isomers and the one examined&#13;
  290. by X-ray crystallography has the fac-PdC3 configuration with the phenyl group trans to the quinoline nitrogen donor. NMR spectra of 8 indicate that the other isomer has the methyl group trans to the quinoline nitrogen donor. Similar geometric isomerism occurs for [Pd(mq)MePh(bpy)]BF4 (4). Structural studies of the dimethylpalladium(IV) complex Pd(mq)Me2{(pz)2BH2} (7) and the platinum(IV) cation in [Pt(mq)Me2(bpy)]BF4.0.75(CH2Cl2) (5) reveal&#13;
  291. similar structures. The cation [Pd(mq)Me2(bpy)]+ is less stable than the methyl(phenyl)palladium(IV) analogue (2), decomposing in (CD3)2CO by reductive elimination to form ethane and 8-ethylquinoline in ~1:2 ratio, together with the Pd(II) products [Pd(mq)(bpy)]Br and PdBrMe(bpy). A complex mixture of 8-substituted-quinolines (saturated and unsaturated substituents) were obtained as the major products of decomposition of [Pd(CH2CH2CH2CH2)(mq)(bpy)]Br (6), consistent with mq...CH2 coupling to give Pd(II) species that undergo further decomposition.</p></div><table style="margin-bottom: 1em" border="0" cellpadding="3" class="not_ep_block"><tr><th valign="top" class="ep_row">Item Type:</th><td valign="top" class="ep_row">Article</td></tr><tr><th valign="top" class="ep_row">Subjects:</th><td valign="top" class="ep_row"><a href="http://eprints.utas.edu.au/view/subjects/259901.html">250000 Chemical Sciences &gt; 259900 Other Chemical Sciences &gt; 259901 Organometallic Chemistry</a></td></tr><tr><th valign="top" class="ep_row">Collections:</th><td valign="top" class="ep_row">UNSPECIFIED</td></tr><tr><th valign="top" class="ep_row">ID Code:</th><td valign="top" class="ep_row">2884</td></tr><tr><th valign="top" class="ep_row">Deposited By:</th><td valign="top" class="ep_row"><span class="ep_name_citation"><span class="person_name">Prof Allan J Canty</span></span></td></tr><tr><th valign="top" class="ep_row">Deposited On:</th><td valign="top" class="ep_row">16 Jan 2008 14:22</td></tr><tr><th valign="top" class="ep_row">Last Modified:</th><td valign="top" class="ep_row">16 Jan 2008 14:34</td></tr><tr><th valign="top" class="ep_row">ePrint Statistics:</th><td valign="top" class="ep_row"><a target="ePrintStats" href="/es/index.php?action=show_detail_eprint;id=2884;">View statistics for this ePrint</a></td></tr></table><p align="right">Repository Staff Only: <a href="http://eprints.utas.edu.au/cgi/users/home?screen=EPrint::View&amp;eprintid=2884">item control page</a></p>
