<meta content="Dimethyl(2,2'-bipyridine)palladium(II) reacted with methyl triflate (CF3SO3Me) at -60 C to form a palladium(IV)
complex which reacted with a range of monodentate phosphines [PPh3, PMePh2, PMe2Ph, PCy3, P(OMe)3],
1,2-bis(diethylphosphino)ethane (depe), or syn,syn-1,5,9-triethyl-1,5,9-triphosphacyclodecane (syn,syn-Et3[12]aneP3)
to form complexes containing octahedral palladium(IV) centres fac-[PdMe3(2,2'-bipy)(L)]+ (1–5, 11–13). The ligand
depe bridges between palladium(IV) centres in a binuclear complex (11), the triphosphine forms both mononuclear (13)
and binuclear species (12), and representative complexes of other bidentate nitrogen donor ligands have also been
prepared, [PdMe3(N–N)(PMe2Ph)][O3SCF3] [N–N = 1,10-phenanthroline (phen) 6 or N,N,N',N'-tetramethylethylenediamine (tmen) (7)]. The first structural analysis of an organopalladium(IV) phosphine complex is reported, and octahedral (6) and platinum(IV) complexes [PtMe3(2,2'-bipy)(L)][O3SCF3] [L = PPh3 (8), PMePh2 (9) or PMe2Ph (1] have been isolated. All of the palladium() complexes reductively eliminate ethane on decomposition to form palladium(II) species, where the monodentate phosphines form [PdMe(N–N)(L)]+ (1a–7a); a structural analysis of square-planar [PdMe(2,2'-bipy)(PMe2Ph)][O3SCF3] (3a) is reported. The stability of palladium(IV) complexes decreases in the order PMe2Ph > PMePh2 > PPh3, and for complexes of PMe2Ph there is a stability order phen > 2,2'-bipy > tmen for [PdMe3(bidentate ligand)(PMe2Ph)]+." name="eprints.abstract" />

complex which reacted with a range of monodentate phosphines [PPh3, PMePh2, PMe2Ph, PCy3, P(OMe)3],
1,2-bis(diethylphosphino)ethane (depe), or syn,syn-1,5,9-triethyl-1,5,9-triphosphacyclodecane (syn,syn-Et3[12]aneP3)
to form complexes containing octahedral palladium(IV) centres fac-[PdMe3(2,2'-bipy)(L)]+ (1–5, 11–13). The ligand
depe bridges between palladium(IV) centres in a binuclear complex (11), the triphosphine forms both mononuclear (13)
and binuclear species (12), and representative complexes of other bidentate nitrogen donor ligands have also been
prepared, [PdMe3(N–N)(PMe2Ph)][O3SCF3] [N–N = 1,10-phenanthroline (phen) 6 or N,N,N',N'-tetramethylethylenediamine (tmen) (7)]. The first structural analysis of an organopalladium(IV) phosphine complex is reported, and octahedral (6) and platinum(IV) complexes [PtMe3(2,2'-bipy)(L)][O3SCF3] [L = PPh3 (8), PMePh2 (9) or PMe2Ph (1] have been isolated. All of the palladium() complexes reductively eliminate ethane on decomposition to form palladium(II) species, where the monodentate phosphines form [PdMe(N–N)(L)]+ (1a–7a); a structural analysis of square-planar [PdMe(2,2'-bipy)(PMe2Ph)][O3SCF3] (3a) is reported. The stability of palladium(IV) complexes decreases in the order PMe2Ph > PMePh2 > PPh3, and for complexes of PMe2Ph there is a stability order phen > 2,2'-bipy > tmen for [PdMe3(bidentate ligand)(PMe2Ph)]+.</p></div><table style="margin-bottom: 1em" cellpadding="3" class="not_ep_block" border="0"><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 > 259900 Other Chemical Sciences > 259901 Organometallic Chemistry</a></td></tr><tr><th valign="top" class="ep_row">ID Code:</th><td valign="top" class="ep_row">2808</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">10 Jan 2008 12:42</td></tr><tr><th valign="top" class="ep_row">Last Modified:</th><td valign="top" class="ep_row">10 Jan 2008 12:42</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=2808;">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&eprintid=2808">item control page</a></p>
