and six-membered chelate rings, while the third one has undergone cleavage across the N=N bond, and the phenolate fragment, thus generated, remains coordinated to the metal center in the iminosemiquinonate form. Structures of four selected complexes have been determined by X-ray crystallography. The first six complexes are one-electron paramagnetic and show rhombic ESR spectra. The last complex is diamagnetic
phenol has been observed upon its reaction with [M(PPh(3))(3)X(2)] (M = Ru, Os; X = Cl, Br) whereby one methyl group from the phenyl ring of the arylazo fragment migrates to the metal center via oxidation to CO.
在与[M(PPh(3))(3)X(2)]反应后,观察到2-(2',6'-二甲基苯基偶氮)-4-甲基苯酚发生了前所未有的化学转化(M = Ru,Os; X = Cl,Br),其中芳基偶氮片段的苯环上的一个甲基通过氧化成CO迁移到金属中心。
