    Phenoxycarbonyl palladium complex was synthesized and its reactivity was investigated relevant to the mechanism of the palladium-catalyzed oxidative carbonylation of phenol to produce diphenyl carbonate (DPC). The phenoxycarbonyl palladium complex PdCl(CO2Ph)(PPh3)2 (1) was synthesized by oxidative addition of phenyl chloroformate to Pd(PPh3)4. Complex 1 could be isolated as single crystals and characterized

    The 1,3-diphosphorus ylide cyclopentadienylium salts (C5H3)(PPh3)2I (1) and (C5H3)[P(4-CH3-Ph)3]2I (2) have been prepared from the reaction of 1,1′-dichloromercurioferrocene with Pd(PPh3)4 and with Pd[P(4-CH3-Ph)3]4, respectively. The molecular structure of 1 has been determined by X-ray diffraction analyses. The Pd(OAc)2/1 or 2/KtOBu system is highly efficient for the coupling reactions of aryl chlorides

  • Synthesis and Structure of η<sup>2</sup>-Phosphonioalkene−Palladium(0) Complexes. A Catalyst Intermediate in the Palladium-Mediated Synthesis of Alkenylphosphonium Halides

    Treatment of Pd(PPh3)(4) with PhCH=CHBr in THF at 45 degrees C gave [(trans-PhCH=CHPPh3)Pd(PPh3)(2)]Br-+(-) (1), which was found to be converted from Pd(PPh3)(2)(CH=CHPh)Br. X-ray structural analysis shows that 1 adopts a distorted-square-planar geometry with two PPh3 ligands and a (PhCH=CHPPh3)(+) moiety. The C-C double bond in the latter is pi-bonded to the palladium(0) center and occupies two of the four square-planar coordination sites. Under similar reaction conditions, Pd[P-trans-PhCH=CHP(p-tolyl)(3)][P(p-tolyl)(3)](2)}Br-+(-) (2) was formed from Pd[P(p-tolyl)(3)](4) and PhCH=CHBr, while [(trans-MeCH=CHPPh3)Pd(PPh3)(2)]Br-+(-) (3) was isolated from the reactions of Pd(PPh3)4 with MeCH=CHBr. Treating PhCH=CHBr with trans-Pd(PPh3)(2)(C6H4O-p-CH3)I in THF at ambient temperature led to the formation of (trans-PhCH=CHPPh3)Pd(PPh3)X (5) and (p-CH3OC6H4PPh3)X-+(-) (X, mixture of Br and I). Complex 5 (X Br) can be prepared by treating trans-PhCH=CH(PPh3)Br-+(-) with Pd(dba)(2) and 1 equiv of PPh3 in CH2Cl2. X-ray analysis shows 5 adopts a distorted-square-planar structure consisting of PPh3, X, and PhCH=CH(PPh3)(+) as ligands. The PPh3 ligand is trans to the olefin carbon that is connected to the PPh3 group in PhCH=CH(PPh3)(+), while the halide ligand is trans to the olefin carbon bonded to a phenyl moiety. Reaction of 5 (X = Br) with 1 equiv of PPh3 at ambient temperature afforded 1 in high yield. Pd(PPh3)(4) or Pd(OAc)(2) catalyzes the reactions of PPh3 with PhCH=CHBr, MeCH=CHBr, MeCH=C(Me)Br (mixtures of isomers), CH2=C(Me)Br, cis-(EtO2C)CH=CHBr, and cis-(MeO2C)CH=CHBr to give the corresponding trans-RCH=CR'(PPh3)Br-+(-). During the reaction of PPh3 with PhCH-CHBr, 1 was found to be a catalyst intermediate in the reaction solution. All the pho sphonioalkene-palladium(0) complexes and alkenylphosphonium halides isolated are trans in the (RCH-CR'PPh3)(+) moiety.
