  摘要：

  报道了利用PNP（PNP ＝ 2，6-双（二叔丁基膦基甲基）吡啶）配体的铂和钯的阴离子，中性和阳离子氢化物配合物的合成和表征。在整个系列中通过IR光谱学和X射线晶体学进行了比较。对阳离子到阴离子配合物的金属氢化物拉伸频率的评估显示出M–H键活化增加的趋势。评估了这些金属氢化物与氧气的反应性，并将其与先前报道的氧气插入反应进行了比较。

  Cationic, Neutral, and Anionic PNP Pd^II and Pt^II Complexes: Dearomatization by Deprotonation and Double-Deprotonation of Pincer Systems

  摘要：

  A series of cationic, neutral, and anionic Pd-II and Pt-II PNP (PNP = 2,6-bis-(di-tert-butylphosphinomethyl)pyridine) complexes were synthesized. The neutral, dearomatized complexes [(PNP*)MX] (PNP* = deprotonated PNP; M = Pd, Pt; X = Cl, Me) were prepared by deprotonation of the PNP methylene group of the corresponding cationic complexes [(PNP)MX][Cl] with 1 equiv of base (KN(SiMe3)(2) or (BuOK)-Bu-t), while the anionic complexes [(PNP**)MX]Y--(+) (PNP** = double-deprotonated PNP; Y = Li, K) were prepared by deprotonation of the two methylene groups of the corresponding cationic complexes with either 2 equiv of KN(SiMe3)(2) or an excess of MeLi. While the reaction of [(PNP)PtCl][Cl] with an excess of MeLi led only to the anionic complex without chloride substitution, reaction of [(PNP)PdCl][Cl] with an excess of MeLi led to the methylated anionic complex [(PNP**)PdMe]Li--(+). NMR studies, X-ray structures, and density functional theory (DFT) calculations reveal that the neutral complexes have a "broken" aromatic system with alternating single and double bonds, and the deprotonated arm is bound to the ring by an exocyclic C=C double bond. The anionic complexes are best described as a pi system comprising the ring carbons conjugated with the exocyclic double bonds of the deprotonated "arms". The neutral complexes are reversibly protonated to their cationic analogues by water or methanol. The thermodynamic parameters Delta H, Delta S, and Delta G for the reversible protonation of the neutral complexes by methanol were obtained.
