  coordination properties of hybrid phosphino-amide ligands o-Ph2PC6H4CONHR [R = iPr (a), Ph (b)] have been investigated. New cyclometallated palladium(II) complexes in which a and b act as P-monodentate ligands have been synthesised by reacting them with selected cyclometallated precursors containing bridging chloride or acetate groups.

  (Arylazo)aryl(acetylacetonato)palladium(II) complexes, [Pd(4-RC6H3N=NC6H4R-4')(O,O-acac)] (R = H 1a, Me 1b or OMe 1c; Hacac = acetylacetone), upon irradiation of their acetone solutions at room temperature by UV, or even long-wavelength visible (lambda > 500 nm) light, were readily oxidized by atmospheric oxygen to give the corresponding acetato derivatives [Pd(4-RC6H3N=NC6H4R-4')(mu-O2-CMe)]2 (R = H 2a, Me 2b or OMe 2c), providing a model for some chemical and biological processes. The oxidation reaction of complex 1b was first order in the complex when [1b]0 less-than-or-equal-to 2 x 10(-3) mol dm-3. Complexes 1b and 1c were photooxidized at approximately twice the rate of complex la. In the presence of a scavenger of C-centred radicals (CCl4) the rate of complex 2b accumulation was reduced. When pyridine was added or co-ordinating solvents (acetonitrile or nitromethane) were used no photooxidation of complex 1 occurred. In the presence of PPh3 an induction period was observed and the oxidation of 1 started only after all the PPh3 was oxidized under irradiation into OPPh3. Spectroscopic data suggested that these ligands inhibit this photochemical oxidation because they change the type of co-ordination of the azobenzene chromophore and/or the acac ligands inducing a disconnection between the chromophore (antenna) and the acac ligand.

  (偶氮芳香基)芳香乙酰丙酮钯(II)配合物，[Pd(4-RC6H3N=NC6H4R-4')(O,O-acac)] (R = H 1a, Me 1b 或 OMe 1c; Hacac = 乙酰丙酮)，当它们的丙酮溶液在室温下受到紫外线或甚至长波可见光(λ > 500 nm)照射时，很容易被大气氧氧化，生成对应的乙酸酯衍生物[Pd(4-RC6H3N=NC6H4R-4')(μ-O2-CMe)]2 (R = H 2a, Me 2b 或 OMe 2c)，为某些化学和生物过程提供了一个模型。当[1b]0 ≤ 2 × 10⁻³ mol dm⁻³时，配合物1b的氧化反应对自身浓度呈一级反应。配合物1b和1c的光氧化速率约为配合物1a的两倍。在存在捕获中心自由基的试剂（CCl4）时，2b的积累速率降低。加入吡啶或使用协同溶剂（乙腈或硝基甲烷）时，1号配合物不会发生光氧化。在PPh3存在下，观察到一个诱导期，1号配合物的氧化仅在所有PPh3在光照下被氧化为OPPh3后才开始。光谱数据显示，这些配体通过改变偶氮苯色团和/或乙酰丙酮配体的配位类型，引起色团（天线）与乙酰丙酮配体之间的断开，从而抑制这种光化学氧化。

  Two series of new dinuclear cyclometallated palladium complexes [Pd(mu-NCO)(C<^>N)}(2)] containing asymmetric imidato NCO- bridging units have been synthesized [C <^> N = azobenzene (azb); -NCO- = succinimide (1a), phthalimide (2a) or maleimide (3a); C <^> N = 2-phenylpyridine (phpy); -NCO- = succinimide (1b), phthalimide (2b) or maleimide (3b)]. The reaction of both succinimidato precursors with tertiary phosphines to form the mononuclear N-bonded imidato derivatives of general Formula [Pd(C <^> N)(suc)(L)] [C <^> N = azb; L - PPh3 (4a), PPh2Me (5a), PPhMe2 (6a), P(4-F-C6H4)(3). (7a), P(4-MeO-C6H4)(3) (8a) C <^> N = phpy L = PPh3 (4b), PPh2Me (5b), PPhMe2 (6b), P(4-F-C6H4)(3) (7b), P(4-MeO-C6H4)(3) (8b)] has been investigated. The new complexes were characterized by partial elemental analyses and spectroscopic methods (IR, FAB, H-1, C-13 and P-31). The single-crystal structures of 1b and 4a have been established.
