The treatment of CpRu(Cl)(PPh3)2 with MeC(O)X offers a very convenient procedure for the synthesis of CpRu(X)(PPh3) 2. The proposed mechanism involves an intermediate produced by the concerted liberation of PPh3 by the incoming MeC(O)X and the subsequent subtraction of the X atom by the Ru atom to form a radical pair.
Ruthenium cyclopentadienyl aryldiazenido complexes. Synthesis of [Cp′Ru(PR3)2(N2C6H 4OMe)][BF4]2 and [Cp′RuCl(PPh3)(N2C6H 4OMe)][BF4] (Cp′ = Cp, Cp*) and x-ray crystal structure of [CpRu(PPh3)2

The neutral ruthenium complexes Cp′Ru(PR3)2Cl [Cp′ = Cp, PR3 = PPh3, PMe3, or 1/2 dppe; Cp′ = Cp*, PR3 = PMe3] react with [p-MeOC6H4N2][BF4] in acetone to give new cyclopentadienyl ruthenium aryldiazenido dicationic complexes [Cp′Ru(PR3)2(N2C6H 4OMe)]-[BF4]2 [Cp′ = Cp, PR3 = PPh3 (1), PMe3 (2), or 1/2 dppe (3); Cp′ = Cp*, PR3 = PMe3 (4)] in good yields. The dicationic complexes 1-3 may also be conveniently isolated in better yield by treatment of the acetonitrile ruthenium complexes [CpRu(PR3)2(NCMe)][BF4] with the arenediazonium salt. When the reaction of Cp′Ru(PPh3)2Cl (Cp′ = Cp or Cp*) with [p-MeOC6H4N2][BF4] is carried out in toluene, the product is instead the cyclopentadienyl ruthenium aryldiazenido monocationic complex [Cp′RuCl(PPh3)(N2C6H 4OMe)][BF4] [Cp′ = Cp (5) or Cp* (6)]. Further, if the reaction of Cp*Ru(PPh3)2Cl with diazonium salt is carried out in acetone, the binuclear complex [Cp*RuCl(N2C6H4OMe)]2[Cl] 2 (7) can be isolated in low yield in addition to 6. All new complexes 1-7 were fully characterized by NMR, FT-IR, and mass spectroscopies. The structure of [CpRu(PPh3)2(N2C6H 4OMe)][BF4]2·0.93CHCl3 (1· 0.93CHCl3) was determined by single-crystal X-ray diffraction. The structure exhibits a near-linear Ru-N-N-C geometry for the coordinated aryldiazenido group, with the NNC angle having a value of 159°, compared to the sp2 value of approximately 120° commonly exhibited by other singly bent aryldiazenido complexes. On the basis of NMR spectroscopic data, 1 reacts with NaBH4 at low temperature to give an arylhydrazido(2-) complex [CpRu(PPh3)2-{NN(H)C6H4OMe}][BF 4], which readily converts to the corresponding aryldiazene complex [CpRu(PPh3)2(NH=NC6H4OMe)][BF 4] by a hydrogen shift; at room temperature, the only product is the hydrido complex CpRuH(PPh3)2.
