  Pt^II-Mediated Imine–Nitrile Coupling Leading to Symmetrical (1,3,5,7,9-Pentaazanona-1,3,6,8-tetraenato)Pt(II) Complexes Containing the Incorporated 1,3-Diiminoisoindoline Moiety

  摘要：

  Treatment of trans-[PtCl2(NCR)(2)] (1; R = Et (1a), Ph (1b)) with 1,3-diiminoisoindoline (2) gives access to the corresponding symmetrical (1,3,5,7,9-pentaazanona-1,3,6,8-tetraenato)Pt(II) complexes [PtCl{NH=C(R)N=C(C6H4)-NC=NC(R)=NH}] (3). The reactions of 1 with one equivalent of 1,1,3,3-tetramethylguanidine (4), 1,3-diphenylguanidine (6), or acetone oxime (8) leads to the formation of mixed asymmetrical Pt(II) complexes trans-[PtCl2{NH=C(R)N=C(NMe2)(2)} (NCR)] (5), [PtCl{NH=C(R)NC(NHPh)=NPh}(NCR)] (7), or trans-[PtCl2{NH=C(Ph)ON=CMe2)(NCPh)] (9), respectively, as a result of nucleophilic addition to one of the nitrile ligands in I. Treatment of 5, 7, and 9 with one equivalent of 2 leads to complexes 3. The complexes were characterized by IR. H-1, C-13{H-1}, and Pt-195 NMR (for 3) spectroscopies, ESI+-MS, elemental analyses, and X-ray diffraction (for 3). Complex 3a has an asymmetric unit with five independent Pt molecules of the same chemical composition and two molecules of water, resulting in a total of 40 molecules of the complex and sixteen guest water molecules per unit cell. Theoretical calculations revealed that the most plausible mechanism of formation of complexes 3 includes stepwise nucleophilic addition of 2 to one of the nitrile ligands in 1, a first cyclization upon formation of the Pt-N bond and elimination of HCl, and a second nucleophilic addition/cyclization.

  Treatment of trans-[PtCl2(NCR)(2)] 1 (R = Me (1a), Et (1b), o-ClC6H4 (1c), p-ClC6H4 (1d), p-(HCdouble bond; length as m-dashO)C6H4 (1e), p-O2NC6H4CH2 (1f)) with 1,3-diiminoisoindoline HNdouble bond; length as m-dashCC(6)H(4)C(NH)double bond; length as m-dashNH 2 gives access to the corresponding (1,3,5,7,9-pentaazanona-1,3,6,8-tetraenato)Pt(II) complexes [PtClNHdouble bond; length as m-dashC(R)Ndouble bond; length as m-dashC(C6H4)NCdouble bond; length as m-dashNC(R)double bond; length as m-dashNH}] 3a-f, in good yields (65-70%). The reaction of trans-[PdCl2(NCMe)(2)] 4a with 2 furnishes (1,3,5,7,9-pentaazanona-1,3,6,8-tetraenato)Pd(II) complex [PdClNHdouble bond; length as m-dashC(Me)Ndouble bond; length as m-dashC(C6H4)NCdouble bond; length as m-dashNC(Me)double bond; length as m-dashNH}] 5a, in good yield (65%). However, the reaction of trans-[PdCl2(NCR)(2)] 4 (R = Ph (4b), p-MeC6H4CH2 (4c), p-(HCdouble bond; length as m-dashO)C6H4 (4d), p-O2NC6H4CH2 (4e)) with 2 gives a number of unidentified products. The compounds 3a-f and 5a were characterized by IR, 1H, 13C and DEPT-135 NMR spectroscopies, elemental analyses and, in the case of the Pt(II) complex [PtClNHdouble bond; length as m-dashC(Me)Ndouble bond; length as m-dashC(C6H4)NCdouble bond; length as m-dashNC(Me)double bond; length as m-dashNH}] 3a, also by X-ray diffraction analysis. Compounds 3a and 3b were also characterized by UV-Vis absorption and luminescence emission spectroscopies. Emission quantum yields of ca. 3 x 10(-3) were obtained in dichloromethane solution, and luminescence lifetimes are in the order of the tens of nanoseconds. Both compounds also exhibited luminescence in solid state (polystyrene matrix), with luminescence lifetimes in the order of hundreds of nanoseconds. (C) 2017 Elsevier Ltd. All rights reserved.
