Low valent palladium benzoquinone complexes bearing different spectator ligands. the versatile coordinative capability of benzoquinone

The synthesis of some benzoquinone palladium complexes bearing different spectator ligands was carried out and the hapticity of the coordinated olefin was inferred from the features of their 1H and 13C NMR spectra. It was shown that benzoquinone coordinates either eta2 and eta4 and that its coordinative choice is not easily predictable, although the eta2 coordination seems to be predominant in the presence of rigid ancillary ligands. The coordinative capability of benzoquinone was tested by means of thermodynamic and kinetic reference reactions and its slightly enhanced inertness with respect to the isofunctional naphthoquinone was assessed. Finally, the re-crystallization by slow diffusion at low temperature of diethylether in a dichloromethane solution of the complex [Pd(eta2-bq)(TTbQ-Me)] (bq = benzoquinone, TTbQMe = 8-t-Butylsulfanyl-2-methyl-quinoline) allows the separation of the dimer [Pd2(eta2-bq)(TTbQ-Me)2] whose solid state structure was resolved.

Novel Di- and Trinuclear Palladium Complexes Supported by N,N?-Diphosphanyl NHC Ligands and N,N?-Diphosphanylimidazolium Palladium, Gold, and Mixed-Metal Copper-Gold Complexes

The reaction of the trinuclear complex [Ag3(mu3-PCNHCP,kappaP,kappaCNHC,kappaP)2](OTf)3 (Ag3; PCNHCP = N,N?-bis(di-tert-butylphosphanyl)imidazol-2-ylidene) with [Pd(dba)2] afforded the trinuclear palladium complex [Pd3(mu3-PCNHCP,kappaP,kappaCNHC,kappaP)2](OTf)2 (Pd3) and the dinuclear palladium(I) complex [Pd2(mu2-PCNHCP,kappaP,kappaCNHC,kappaP)2](OTf)2 (Pd2). The assignment of the oxidation state of the metals in the mixed-valence Pd3 chain as Pd0-PdII-Pd0 was based on the reactivity of the complex with 2,6-dimethylphenyl isocyanide and density functional theory calculations. Reaction of PCNHCP with [PdMe2(tmeda)] afforded the palladium(II) complex [PdMe2(PCNHCP,kappaP,kappaCNHC)] (Pd-Me2), with PCNHCP acting as a bidentate ligand. The reaction of PCNHCP with [Pd(dba)2] led to a dinuclear palladium(0) complex [Pd2(mu2-PCNHCP,kappaP,kappaCNHC,kappaP)](dba) (Pd2-dba); attempted replacement of the remaining dba by PCNHCP failed. The imidazolium triflate PCHP, precursor to PCNHCP, was reacted with [Pd2(dba)3]¡¤CHCl3 to give the (2 + 2) metalla-mesocyclic cationic palladium(0) complex [Pd2(mu2-PCHP,kappaP,kappaP)2] (PCHP-Pd2), which resisted further deprotonation of the imidazolium cation. In contrast, PCHP reacted with [AuCl(tht)] to give [Au2Cl2(mu2-PCHP,kappaP,kappaP)] (PCHP-Au2), in which one Au-Cl moiety is bound to each P donor. Further reaction of PCHP-Au2 with [Au{N(SiMe3)2}(PPh3)] afforded a mixture of the trinuclear [Au3(mu3-PCNHCP,kappaP,kappaCNHC,kappaP)2](OTf)3 (Au3) and [AuCl(PPh3)], while reaction with [CuMes]5, where Mes = 2,4,6-trimethylphenyl, resulted in a novel, centrosymmetric, heterometallic complex [Au2Mes2(Cu4Cl4)(PCHP,kappaP,kappaP)2] (PCHP-AuCu) featuring a new PCHP-AuMes metalloligand bridging a Cu¡¤¡¤¡¤Cu diagonal of a Cu4Cl4 cubane via the P and AuMes functionalities.

[Pt(CO)x]n (x?2), the already described species obtained by the reaction of platinum(0) olefin complexes with carbon monoxide, reacts promptly at room temperature with SO2Cl2 under CO affording cis-PtCl2(CO)2. [Pd2(CO)y]n (y?1), obtained by Pd(dba)2 and CO at room temperature, reacts in the same conditions yielding Pd2Cl4(CO)2. Similarly, although more slowly, finely divided platinum and palladium, in the form of metal blacks, react with SO2Cl2 and CO at room temperature producing again cis-PtCl2(CO)2 and Pd2Cl4(CO)2, respectively. In the absence of CO no reaction is observed within 4 weeks.

Chiral amino alcohol derived bis-phosphoramidite pincer palladium complexes and their applications in asymmetric allylation of aldimines

Novel P-stereogenic bis-phosphoramidite pincer palladium complexes 1 and 2 derived from (S)-(-)-alpha,alpha-diphenyl-2-pyrrolidinemethanol and (S)-(+)-indolinemethanol, respectively, were synthesized in reasonable yields (i.e., 55-62%) by using a flexible, modular synthetic approach and were characterized by X-ray crystal structure determination. Reacting (S)-(+)-indolinemethanol with PCl3 leads to the formation of a novel P-chiral building block, which exhibits good thermal stability of its stereochemical features. This enabled the design and development of new P-chiral bisphosphoramidite pincer arene ligands and their corresponding metal complexes. The molecular structure of the new indolinemethanol-derived phosphoramidite pincer metal complex screens quadrants I and III, which is in contrast to the previously reported L-proline-derived P-chiral ligands that screen quadrants II and IV. The bis-phosphoramidite pincer palladium, complexes 1 and 2 are active catalysts for asymmetric homoallylation of sulfonimines, where low (ee 33%) or no enantioselectivity was observed for reactions catalyzed by 2 and 1, respectively. Preliminary catalytic results revealed that enantiomeric excess values varied by using differently functionalized sulfonimines, suggesting that, both electronic properties and steric congestion of sulfonimines affect, the transition state of the electrophilic attack of the 1nallyl Pd intermediate in the allylation.
