  SYNTHESIS AND CHARACTERIZATION OF RUTHENIUM(II) PYRAZOLE TERTIARY PHOSPHINE COMPLEXES

  摘要：

  The product of the reaction of [RuCl2(PPh3)(3)] with two equivalents of pyrazole (Hpz) in toluene, when precipitated from a toluene/hexane mixture was characterised as [RuCl2(Hpz)(2)(PPh3)(2)] . 1/2C(6)H(14) (1); the same reaction, effected in acetone, produced the acetone coordinated species [RuCl2(Hpz)(Me2CO)(PPh3)(2)] (2). When the reaction was carried out using 3,5-dimethylpyrazole (HDMpz), in either acetone or toluene as solvent, the yellow five-coordinate complex [RUCl2(HDMpz)(PPh3)(2)] (3) was produced. The bromo compounds [RuBr2(Hpz)(2)(PPh3)(2)] . 1/2C(6)H(14) (4) and [RuBr2(HDMpz)(PPh3)(2)] (5) have also been prepared using [RuBr2(PPh3)(3)] as precursor. Attempts to make the iodo analogues from [RuI2(PPh3)(2)](n), resulted in a species identified as [RuI2(HDMpz)(PPh3)(2)] on the basis of NMR and infrared measurements. The novel derivatives (1)-(5) have been characterised using microanalyses and infrared, H-1 and P-31 NMR spectroscopy.Reaction of (1) with CO resulted in displacement of Hpz to eventually produce cis-[RuCl2(CO)(2)(PPh3)(2)]. The reaction appeared to proceed through the a monosubstituted product [RuCl2(CO)(Hpz)(PPh3)(2)], distinguished from spectroscopic measurements. The reaction of (1) with oxygen is discussed.
