The oxygenolysis of 9,10-phenanthrenequinone by CuXL [X = Cl or Br; L = pyridine (py), 2,2′-bipyridine (bipy), and 1,10-phenanthroline (phen)] to well defined mixed-ligand diphenatocomplexes [Cu2X2(C14H8O4)Ln](n= 4, L = py; n= 2, L = bipy or phen) is reported. In the reaction of the quinone with preformed copper–dioxygen complexes under argon half of the copper was converted into the diphenatocopper
CuXL [X = Cl或Br; L =吡啶(py),2,2'-联吡啶(bipy)和1,10-菲咯啉(phen)]为定义明确的混合配体联苯复合物[Cu 2 X 2(C 14 H 8 O 4)L n ] (n = 4,L = py;n = 2,L = bipy或phen)。在氩气下,醌与预先形成的铜-二氧配合物反应,一半的铜被转化为苯乙酮配合物,另一半被分离为CuXL或CuXL 3配合物。讨论了氧解的可能模式。

A method of attaching one or more organic groups onto a particle is described which involves reacting at least one radical with at least one particle wherein the radical is generated from the interaction of at least one transition metal compound with at least one organo-halide compound in the presence of one or more particles capable of radical capture. Variations of this method are also described.
Methylchloroformate synthesis via direct interaction of palladium di(methoxycarbonyl) complexes with CuCl2: Utilization in the synthesis of carbonates and carbamates
ClCOOCH3 has been obtained in very good yield by -action of [PdL2(COOCH3)2] [L2 = 2,2'-bipyridine (bipy) or 1,10-phenanthroline (phen)] with CuCl2. The in situ reaction of ClCOOCH3 with alcohols or amines produces carbonates or carbamates.

The reactivity of mono- and di-methoxycarbonyl complexes of palladium of formula [PdL2Cl2-n(COOCH3)n] (n = 1 or 2; L2 = chelating ligand) towards amines in the presence of [RNH3]Cl or CuCl2 has been studied. The reactions yield N,N'-disubstituted ureas or carbamates, respectively. These results are compared with the dioxygen-induced carbonylative oxidation of amines catalyzed by palladium-based systems.
