  Enhanced Stability of a Paramagnetic Palladium Complex Promoted by Interactions with Ethynyl Substrates

  摘要：

  The highly reactive palladium-centered radical cluster [Pd-3(dpPM)(3)(CO)](center dot+) exhibits only a limited stability in solution at room temperature (about an hour). This stability can be extended significantly to several hours by adding organic substrates such as the symmetric and asymmetric alkynes Ph-C C-H and MeO2C-C C-CO2Me, which reversibly bind to the Pd-3 triangle. The presence of the substrate inside the cavity protects the palladium centers from reacting with the "outside world", hence enhancing the stability. Both adducts are stable as the cluster is always totally recovered. The paramagnetic complexes along with their corresponding dications were characterized by EPR, variable-temperature P-31 NMR, UV-vis and MALDI-TOF spectroscopy, and electrochemistry. For the MeO2C-C C-CO2Me/[Pd-3-(dppm)(3)(CO)](2+) complex, the analysis of the low-temperature P-31 NMR spectra strongly suggests a major structure modification of the ligand and substrate with respect to the starting materials.

  The title clusters, Pd 3 (dppm) 3 (CO) + and Pd 3 (dppm) 3 (CO) 0 can be electrochemically generated from the 1- and 2-electron reductions, respectively, of the Pd 3 (dppm) 3 (CO) 2 + cluster [dppm = bis(diphenylphosphanyl)methane; Pd 3 2 + ]. Pd 3 + reacts in a stoichiometric ratio with methyl iodide, MeI, and benzyl bromide, BzBr, in THF to provide the corresponding Pd 3 (X) + adducts (X = I, Br

  标题簇 Pd 3 (dppm) 3 (CO) + 和 Pd 3 (dppm) 3 (CO) 0 可以分别从 Pd 3 (dppm) 3 ( CO) 2 + 簇 [dppm = 双（二苯基膦基）甲烷；Pd 3 2 + ]。Pd 3 + 以化学计量比与甲基碘 MeI 和苄基溴 BzBr 在 THF 中反应以提供相应的 Pd 3 (X) + 加合物（分别为 X = I、Br）作为无机产物。对于 BzBr，其他产品是 Bz 2 和 PhMe，但对于 MeI，没有观察到有机产品（因为它们太易挥发）。在相同底物的存在下，Pd 3 0 也以化学计量比反应形成相同的有机物和 Pd 3 -(X) + 加合物（X = I 和 Br）。然而，对于 Mel，主要的无机产物是 A-frame Pd 2 (dppm) 2 (Me) 2 I + 双核复合物。对于溴化溴，无法检测到相应的 A 框架复合物 Pd 2 (dppm)

  The stoichiometric and catalytic activations of alkyl halides and acid chlorides by the unsatured Pd(3)(dppm)(3)(CO)(2+) cluster (Pd(3)(2+)) are investigated in detail. A series of alkyl halides (R-X; R = t-Bu, Et, Pr, Bu, allyl; X = Cl, Br, I) react slowly with Pd(3)(2+) to form the corresponding Pd(3)(X)(+) adduct and "R(+)". This activation can proceed much faster if it is electrochemically induced
