  摘要：

  摘要使用空间受限的1,2-双（二叔丁基膦基）乙烷（dtbpe）配体，形成了一般形式（dtbpe）PtX（NHAr）的末端苯胺基化合物家族（X = Cl，2; Me，6 ;（Ph，7; Ar = 2,6-二异丙基苯基）以及（dtbpe）Pt（NHPh）2（8）是通过使用（dtbpe）PtCl2进行盐复分解以高分离产率制备的。同样，制备了新的立体式末端磷酸酯化合物，其通式为（dtbpe）PtX（PHAr）（X / Ar = Cl / dmp，9; Cl / Mes ∗，10; Me / Mes ∗，11;其中dmp = 2 ，6-二甲苯基苯基，Mes ＝ 2,4,6-三叔丁基苯基）。这两类化合物都可以抵抗用外部碱基或通过烷烃或芳烃消除使酰胺或磷配体去质子化的尝试。化合物11与各种酸反应，得到具有阳离子[（dtbpe）PtMe（PH2Mes ∗）] + [12] +的盐。化合物6、9·0.5Et2O，10·Et2O，

  complexes were tested in the Baeyer−Villiger oxidation of 2-methylcyclohexanone, 2-methylcyclopentanone, and cyclobutanone with 35% hydrogen peroxide as oxidant. The reactions were performed at 20 and 70 °C in a chlorinated solvent/H2O two-phase system. Within the above-reported series of complexes, 1e gave the highest catalytic activity and productivity in the oxidation of cyclic ketones. The Lewis

  Protonation of the complexes [PtR2(L-L)] [R = Me, L-L = (C6H11)2P(CH2)3P(C6H11)2 1a; Bu2(t)P(CH2)3PBu2(t), 1b; Bu2(t)P(CH2)1PBu2t 1c; or Bu2(t)PCH2C6H4CH2PBu2(t), 1d; R = CH2Bu(t), L-L = (C6H11)2P(CH2)3P(C6H11)2, 2a; Bu2(t)P(CH2)3PBu2t, 2b; or Bu(t)2P(CH2)2PBu(t)2, 2c] with the monocarbaborane acid HCB11H12 in diethyl ether at 0-degrees-C affords the exo-diphosphineplatinum-closo-monocarbaborane complexes [Pt(L-L)(closo-CB11H12)][CB11H12] [L-L = (C6H11)2P(CH2)3P(C6H11)2, 3a, Bu(t)2P(CH2)3PBu(t)2, 3b; Bu(t)2P(CH2)2PBu(t)2 3c; or Bu(t)2PCH2C6H4CH2PBu(t)2, 3d] in which the coordinated closo-CB11H12 ligand is strongly bound to platinum via two exo-polyhedral three-centre two-electron (Pt...H...B) bridges. These complexes are fluxional in solution at room temperature. A single-crystal X-ray diffraction study of 3c confirmed the bonding mode of the dodecarborane ligand. Complex 3c crystallizes in the monoclinic space group C2/c, a = 16.199(4), b = 16.564(5), c = 14.896(3) angstrom, beta = 93.64(2)-degrees and Z = 4. The final discrepancy index was R = 0.043, R' = 0.050 for 2838 independent reflections. The geometry around the platinum centre is distorted square planar with mu-H-Pt 1.90(8), Pt-B 2.342(8) and B-mu-H 1.23(8) angstrom. In contrast when the solvent is changed from ether to tetrahydrofuran (thf), complex 1b on protonation is converted into [PtMe(thf)Bu(t)2P-P(CH2)3PBu(t)2}][CB11H12] 5. Complexes 3b-3d react with acetonitrile to yield [Pt(NCMe)2(L-L)]-[CB11H12]2[L-L = Bu(t)2P(CH2)3PBu(t)2, 6b; Bu(t)2P(CH2)2PBu(t)2, 6c; or Bu(t)2CH2C6H4CH2Bu(t)2, 6d]. Likewise 3b reacts with pyridine affording [Pt(NC5H5)2Bu(t)2P(CH2)3PBu(t)2}][CB11H12]2 7. However C2H4, CO and PPh3 do not react readily with these complexes. The thf complex 5 reacts with deuteriated acetonitrile to form [PtMe(NCCD3)Bu(t)2P(CH2)3PBu(t)2}][CB11H12] 8. Spectroscopic data for the new complexes are presented and discussed.
