Cyclic voltammetry is used to study 1,1-bis(diarylphosphino)metallocenes (PP) [M(5-C5R4PAr2)2] (M = Fe; R = H; Ar = Ph, o-MeOC6H4, o-PrOC6H4, C6F5; M = Fe, R = Me, Ar = Ph; M = Ru, Os; R = H, Ar = Ph) and such Pd(II) complexes with these as neutral dichlorides [(PP)PdCl2], dication solvates [(PP)Pd(L)
n
]2+ (L = H2O, MeCN), and dication triphenylphosphines containing metal–Pd bond (PP)Pd(PPh3)]2+. The nature of the metallocene metal atom and aryl substituents at phosphor atoms and the formation of a metal–Pd bond affect redox potentials of these compounds. 1,1-bis(Diphenylphosphino)metallocenes [M(5-C5H4PPh2)2] (M = Fe, Ru, Os) feature similar electron-donating properties. Oxidation potentials of Pd(II) complexes can serve as a criterion indicating the formation of a metal–Pd bond. 相似文献

The properties of the ruthenium (II) phosphine complexes [Ru(dppe)2(OTs)2] and [Ru{PhP(CH2CH2CH2PPh2)2}(OTs)2] as catalysts of alternating copolymerization of ethylene and carbon monoxide were studied. The catalytic activity of these
complexes in the absence of cocatalysis is low, but it is substantially increased in the presence of trifluoroacetic acid
or 1,4-benzoquinone. These compounds are the first ruthenium complexes which catalyze copolymerization of ethylene and CO.
