  摘要：

  Ruthenium, palladium and platinum complexes of 2,2,6,6-tetramethyl-3,5-heptanedione (thd) and ruthenium tris acetylacetonate (acac) were synthetized and studied with TG, DTA, DSC and MS methods. Thermal properties of ruthenocene were also studied. The platinum thd complex has the highest volatility despite the second highest molecular mass of the complex. All the complexes sublimed under reduced pressure. Ru(acac)3 decomposed during sublimation under atmospheric pressure of nitrogen whereas the other compounds studied sublimed also under these conditions. Pd(thd)(2) reduced under atmospheric pressure of H-2/N-2 (5% H-2) whereas the ruthenium complexes were not reduced. The field desorption mass spectra of complexes showed only the molecular peaks and no fragmentation occurred.

  bis(diphenylphosphino)methanido complexes, [M(Ph2PCHPPh2)2], through deprotonation of dppm by the displaced acac anions. The analogous complexes, [M(Ph2PC(Me)PPh2)2], are obtained using mdppm, instead of dppm. A complete reaction scheme leading to these products is proposed, based on the IR and 1H, 13C, and 31P NMR spectral data. Some consideration is given to the dependence of these reactions on the metals and

  [M(β-dik)2] (M=Pt(II), Pd(II); β-dik=乙酰丙酮 (acac), 二戊酰甲烷 (dpm), 六氟乙酰丙酮 (hfac) 离子) 与 dppm (dppm= Ph2PCH2PPh2)和mdppm(mdppm=Ph2PCH(Me)PPh2)已被研究。[M(hfac)2] 复合物与 dppm 反应生成稳定的阳离子复合物 [M(dppm)2](hfac)2。相比之下，[M(acac)2] 配合物通过被置换的 acac 阴离子对 dppm 进行去质子化，产生均配的双（二苯基膦基）甲氧基配合物 [M(Ph2PCHPPh2)2]。类似的复合物 [M(Ph2PC(Me)PPh2)2] 是使用 mdppm 而不是 dppm 获得的。根据 IR 和 1H、13C 和 31P NMR 光谱数据，提出了产生这些产物的完整反应方案。考虑到这些反应对金属和所采用的 β-二酮配体的依赖性。
