  摘要：

  Pd(PEt3)2(OTf)2, acting as an in situ source of Pd(PEt3)2, reacts with an alkyne and hydrogen via phosphine loss to form the detectable hydride-containing species Pd(PEt3)2(H)(CHPhCH2Ph), cis- and trans-Pd(PEt3)2(H)(CPh=CHPh), and Pd2(PEt3)3(H)(CHPhCH2Ph)2+, which map onto the reaction scheme predicted by density functional theory.

  hitherto unknown bis(4-pyridyl)silanes 2a,b with bis(triethylphosphine)platinum and bis(triethylphosphine)palladium bistriflates 5a,b lead to the formation of new silicon-containing rhomboids 6a−d. In addition, a similar carbon analogue 7 was prepared by reaction of bispyridyl acetal 4 and bis(triethylphosphine)platinum bistriflate (5a). Surprisingly, reaction of the bis(4-pyridyl)ketone (3) and the platinum

• Diastereomeric Square-Planar Platinum(II) and Palladium(II) Complexes Due to Restricted Rotation about the Chelated M-N Heteroaryl Bond
  作者：Peter J. Stang、Bogdan Olenyuk、Atta M. Arif

  The reaction of 3-bromopyridine, quinoline, or isoquinoline with cis-M(L)(2)(OTf)(2) (M = Pd, Pt; L = triethylphosphine, 1/2 1,3-bis(diphenylphosphino)propane (dppp) or 1/2 (R)-(+)-2,2'-bis(diphenylphosphino)-1,1'-binaphthyl ((R)-(+)-BINAP)) results in the formation of diastereomeric, square-planar, cationic complexes, which exhibit restricted rotation about the metal-nitrogen heteroaryl bond. All complexes were characterized by routine physical and spectroscopic methods, of which P-31(H-1) NMR spectroscopy was most valuable. Only the complexes [Pd(dppp)(isoquinoline)(2)][OTf](2) (14), [Pt(dppp)(isoquinoline)(2)][OTf](2) (15), and [Pd((R)-(+)-BINAP)(isosqinoline)(2)][OTf](2) (22) were found to be dynamic at ambient temperature on the NMR time scale. Variable-temperature studies of the P-31(H-1) NMR spectra of these compounds were performed. The X-ray crystal structure of [Pt(dppp)(quinoline)(2)][OTf](2) (19) in one of its stereoisomeric (syn) forms is reported. [Pd((R)-(+)-BINAP)(isoquinoline)(2)][OTf](2) (22) and [Pt((R)-(+)-BINAP)(isoquinoline)(2)][OTf](2) (23) exhibit three distinct rotamers at -20 degrees C and ambient temperature, respectively. The role of asymmetric induction of the chiral bis-phosphine ligand on the stereoisomeric ratio of the rotamers of 22 and 23 is discussed.
