  Synthesis of Neutral Molecular Squares Composed of Bis(phosphine)platinum Corner Units and Dialkynyl Linkers. Solid-State Characterization of [Pt(μ-C⋮CC⋮C)(dppp)]₄

  摘要：

  Coupling of dichloroplatinum complexes with ethyne or butadiyne, catalyzed by CuI in the presence of Et2NH, leads to complexes of the types [Pt(C=CH)(2)L-2] (L-2 = dppe (1), dppp (2); L = PEt3 (3)) and [Pt(C=CC=CH)(2)L-2] (L-2 = dppp (4), dcpe (5); L = PEt3 (6)). Attempts to produce tetraplatinum species with ethynyl edges proved unsuccessful, but further coupling of the butadiynylplatinum complexes with [PtCl2L2] produces the neutral molecular squares [Pt(mu-Cequivalent toCCequivalent toC)(2)L-2](4) (L-2 = dppp (7), dcpe (8); L = PEt3 (9)). This two-step approach allows the synthesis of the unsymmetrical complexes [Pt-2(mu-Cequivalent toCCequivalent toC)(2)(PEt3)(2)L-2] (L-2 = dppp (10); dcpe (11)). The molecular structure of 7 reveals that each square has a puckered, butterfly-like structure. These pack in a face-to-face manner, generating series of channels that accommodate several solvent molecules. Coupling of trans-[Pt(Cequivalent toCCequivalent toC)(2)(PEt3)(2)] (6b) with [PtCl2L2] (L-2 = dcpe, dppp) leads to complexes assigned as neutral octaplatinum derivatives. The nitrogen-containing complexes [Pt(C=CC5H4N)(2)(dppp)] (14) and [Pt(Cequivalent toCC(6)H(4)CN)(2)(dppp)] (15) react with AgNO3 to produce Pt4Ag4 adducts.

  High-yield syntheses of two new types of platinum (II) alkenyl compounds are described: (i) organoboration of trans-[Pt(CC–H)2(PEt3)2] with R13B (R1= Me, Et, or Pri) leads to (E,E)-trans-[Pt(CHCR1BR12)2-(PEt3)2] and (ii) organoboration of trans-[Pt(CC–Me)2(PEt3)2] with R13B (R1= Me or Et) leads to (E)-trans-[Pt(CC–Me)(CMeCR1BR12)(PEt3)2].

  2Pt(C≡C)3SiEt3 (PtC6TES) is converted in situ to PtC6H (wet n-Bu4N+ F−, THF) and cross coupled with the diyne H(C≡C)2SiEt3 (HC4TES; CuCl/TMEDA, O2) to give PtC10TES (71 %). This sequence is repeated twice to afford PtC14TES (65 %) and then PtC18TES (27 %). An analogous series of reactions starting with PtC8TES gives PtC12TES (60 %), then PtC16TES (43 %), and then PtC20TES (17 %). Similar cross couplings
