Four three-coordinate arylpalladium amido complexes with a single hindered phosphine were isolated and structurally characterized. Each possessed a T-shaped geometry. Several of these complexes possessed true three-coordinate structures that lacked any additional coordination by ligand C-H bonds. All of the three-coordinate complexes underwent reductive elimination to form the corresponding triarylamine. A comparison of the rate of reaction of the three-coordinate compounds demonstrated that the rate of elimination from the pentaphenylferrocenyl di-tert-butylphosphine complex were the fastest. A comparison of the rates of reactions between three-coordinate and four-coordinate complexes showed that the rates were much faster from the three-coordinate complexes. Copyright

Kinetic, spectroscopic and computational studies examining a palladium-catalyzed imidoylative coupling highlight the dual role of isocyanides as both substrates and ligands for this class of transformations. The synthesis of secondary amides from aryl halides and water is presented as a case study. The kinetics of the oxidative addition of ArI with RNC-ligated Pd0species have been studied and the resulting imidoyl complex [(ArC=NR)Pd(CNR)2I] (Ar=4-F-C6H4, R=tBu) has been isolated and characterized by X-ray diffraction. The unprecedented ability of this RNC-ligated imidoyl-Pd complex to undergo reductive elimination at room temperature to give the amide in the presence of water and an F?/HF buffer is demonstrated. Its behavior in solution has also been characterized, revealing an unexpected strong tendency to give cationic complexes, and notably [(ArC=NR)Pd(CNR)3]+with excess isocyanide and [(ArC=NR)Pd(PP)(CNR)]+with bidentate phosphines (PP). These species may be responsible for catalyst deactivation and side-reactions. Ab initio calculations performed at the DFT level allowed us to rationalize the multiple roles of RNC in the different steps of the catalytic cycle.

The divergent synthesis of star-shaped oligophenylene dendrimers is described. These latter consist of a triptycene central core decorated with various peripheral tetra- and octa-arylamine derivatives. The target compounds were prepared via a convenient [4 + 2] Diels?Alder cycloaddition reaction followed by palladium-catalyzed Buchwald?Hartwig Cross-Coupling reactions in very good overall yields. The dendritic structures were confirmed by 1H- and 13C-nuclear magnetic resonance, high resolution mass spectrometry, and thermogravimetric analysis. Photophysical studies of these star-shaped dendrimers revealed their violet and blue fluorescent properties, thus, promoting them as promising materials for emission applications.

The reaction of [Pd(dtbpf)Cl2] (dtbpf = 1,1?-bis(di-tert- butylphosphino)ferrocene) with a chemical oxidant led unexpectedly to the formation of [Pd(dtbpf)Cl]+. Further study found that a variety of reagents could be used to abstract a chloride ligand from [Pd(dtbpf)Cl 2] to yield [Pd(dtbpf)Cl]+. The solid-state structure suggests the formation of an Fe-Pd interaction. The presence of the bulky tert-butyl groups is essential, as similar reactions with [Pd(PP)Cl2] (PP = other 1,1?-bis(phosphino)ferrocene ligands) results in the formation of [Pd(PP)(mu-Cl)]22+. The analogous platinum compounds have also been investigated and appear to behave in a similar manner. Similar compounds of the type [M?(PP)(PR3)]2+ (M? = Pd, Pt, R = Ph, Me) have been prepared, and a metal-metal interaction has also been observed. Steric and electronic effects dictate the formation of these compounds. X-ray crystal structures were obtained for eight of these compounds and were used as the basis for a computational analysis of the metal-metal interaction. DFT analysis indicates the presence of a weak, noncovalent interaction between the two metal centers. The electrochemical properties of these compounds were examined by cyclic voltammetry and typically show one oxidative wave and either one two-electron or two one-electron reductive waves.

The platinum(0)-diphosphine complex [Pt(CO)(L1)] (3, where L1 = 1,2-C6H4(CH2PtBu2)2) and its diphosphinite analogue [Pt(CO)(L2)] (11, where L2 = 1,2-C6H4(OPtBu2)2) act as Lewis bases in conjunction with the main group Lewis acid B(C6F5)3 to form frustrated or cooperative Lewis pairs. These systems activate dihydrogen, ethene/carbon monoxide, and phenylacetylene, leading to products that depend on the exact ligand used. These subtle changes to ligand structure influence reactivity, most notably in hydrogen activation where a variety of dinuclear species of the type [(diphos)Pt(mu-H)3Pt(diphos)]+ or [(diphos)Pt(mu-H)(mu-CO)Pt(diphos)]+ are observed. Activation of ethene with the Lewis pair leads to a previously reported coupling product and the mechanism is probed. The basicity of [Pt(CO)(L)] is demonstrated by deprotonation of phenylacetylene. Preliminary studies with an analogous palladium complex [Pd(CO)(L1)] 33 suggests related chemistry may be exploited for this metal. These results provide further examples of cooperative Lewis pair behavior in which one of the components is based on a transition metal complex.
