nitrido complexes of ruthenium and osmium
نویسنده
چکیده
Ru=O complexes have been demonstrated to be competent oxidants for oxidation of saturated hydrocarbons and epoxidat ion of alkenes . Photoexcitation of transdioxoosmium(V1) gives rise to super-oxidizing complexes having EO >2.2 V vs. n.h.e.. Some cationic RuZN and OsZN complexes are good model system for study of the mechanism of metalcatalysed oxidation of ammonia to nitrite and activation of diiiitrogen molecule. With 2,3-diamino-2,3-dimethylbutane as l igand, reversible Os(1V)-amide/Os(III)-amine and Ru(V)imido/Ru(II)-amine redox couplexes are observed.

Highly electrophilic (salen)ruthenium(VI) nitrido complexes.
A series of cationic ruthenium(VI) nitrido species containing the cyclohexyl-bridged salen ligand (L) and its derivatives, [RuVI(N)(L)]+, have been prepared by treatment of [NBun4][RuVI(N)Cl4] with H2L in methanol. The structure of [RuVI(N)(L)](ClO4) (1a) has been determined by X-ray crystallography, d(RuN) = 1.592 A. In solvents such as DMF or DMSO, [RuVI(N)(L)]+ undergoes a facile N...N coupl...

متن کاملA multinuclear 1H, 13C and 11B solid-state MAS NMR study of 16- and 18-electron organometallic ruthenium and osmium carborane complexes.
The first (1)H, (13)C, (31)P and (11)B solid state MAS NMR studies of electron-deficient carborane-containing ruthenium and osmium complexes [Ru/Os(p-cym)(1,2-dicarba-closo-dodecaborane-1,2-dithiolate)] are reported. The MAS NMR data from these 16-electron complexes are compared to those of free carborane-ligand and an 18-electron triphenylphosphine ruthenium adduct, and reveal clear spectral d...
متن کاملDinuclear ruthenium nitrido complexes supported by an oxygen tripodal ligand.
Dinuclear ruthenium nitrido complexes supported by the Kläui's tripodal ligand [CpCo{P(O)(OEt)(2)}(3)](-) (L(OEt)(-)) have been synthesized starting from the ruthenium(VI) nitrido precursor [L(OEt)Ru(VI)(N)Cl(2)] (1). Heating a solution of 1 in CCl(4) at reflux, followed by recrystallization from hexane under nitrogen, afforded the mixed-valence ruthenium(V)-ruthenium(IV) μ-nitrido complex [L(O...
