该化合物可通过过量的亚苄基丙酮与醋酸钠和氯钯酸钠在热的甲醇溶液(大约60°C)中反应制备[3]。这种络合物呈黑紫或棕色,因此常用氯仿重结晶得到色素较少的产物,而供应的商品也通常是氯仿的加合物Pd2(dba)3·CHCl3。 在Pd2(dba)3中,两个Pd原子相隔320pm,并通过dba单位连接起来[4]。零价钯中心分别连接dba配体...
Crystal structure of Pd2(dba)3 has been determined by three-dimensional X-ray data. Crystals of Pd2(dba)3 are reported to crystalize in triclinic system. It is widely used Pd(0) source in Pd-mediated transformations. • Catalyst for Suzuki coupling of aryl chlorides (eq. 1) • ...

The solid-state structures of three Pd02(dba-Z)3 complexes (4-F, 4-OMe, 3,5-OMe) have been determined by single crystal X-ray diffraction methods, which have been compared with Goodson's X-ray structure of Pd02(dba-4-OH)3.Journal of the American Chemical Society...
Synthesis, Characterization and Properties of Transition Metal Pd/Pt [60]Fullerene Complexes Containing Phosphane Ligands Crystal Structure of [Pd(η 2 -C ... A solution of C60 in toluene reacts with Pd(dba)2 or Pd2(dba)3 (dba = dibenzylideneacetone) and monophosphanes in a 1:1:2 molar...
X-ray crystallography on as-grown platelets gives a crystal structure consistent with Pd2(dba)3, but reveals a composition of ≈Pd1.07(dba)3, indicating one Pd atom in Pd2(dba)3 is lost from the structure. Both electron beam and thermally induced decomposition of as-grown Pd2(dba)3 ...
The cross-coupling of aliphatic and aromatic thiols and aryl bromides/triflates mediated by a Pd2(dba)3/Xantphos catalytic system in refluxing xylene (140 °C) affords the corresponding aryl thioethers in good to excellent yields. Graphical Abstract Download: Download full-size image ...
As-grown hexagonal platelets formed from a Pd2(dba)3 precursor are shown to be disordered microcrystals containing 1–2 nm Pd clusters, which grow and transform into Pd nanocrystals under an electron beam or through thermal annealing. In-depth investigation of the crystal structure and ...
A catalyst comprised of Pd2(dba)3·CHCl3 and an N–Ar axially chiral mimetic-type ligand, (S)-N-[2-(diphenylphosphanyl)naphthalene-1-yl]-2-(piperidinylmethyl)piperidine, provides good enantioselectivities for the asymmetric Kumada–Corriu cross-coupling reaction of 1-phenylethylmagnesium chloride ...
