Bench-stable solid triorganoindium compounds have been prepared by coordination with 4-(dimethylamino)pyridine (DMAP). The solid R3In(DMAP) complexes are obtained from the corresponding solution of R3In in quantitative yield and can be stored for up to several weeks. These reagents show excellent reactivity in palladium-catalyzed cross-coupling reactions with organic electrophiles.

Application of 32005-36-0, A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 32005-36-0, Name is Bis(dibenzylideneacetone)palladium, molecular formula is C34H28O2Pd.

The catalytic synthesis of isobutanol (iBuOH), via the Guerbet condensation of methanol with n-propanol is described. In particular, bifunctional catalysts based on either heterogeneous or homogeneous dehydrogenating/hydrogenating palladium species and on sodium methoxide (MeONa) as basic component were investigated. When heterogeneous Pd/C and MeONa was used as catalytic system a high activity was obtained with turnover numbers up to about 110mol of iBuOH/(mol of Pd h). The increase of the MeONa/Pd molar ratio increased the activity of the catalyst. However, differently from Cu-based/MeONa catalysts, a significant metal leaching was observed; recycle experiments indicated that both heterogeneous and homogeneous palladium species are involved in the catalysis. When homogeneous palladium complexes, such as tetrakis(triphenylphosphine)palladium(0) [Pd(PPh3)4] diphenylphosphinoethane(dichloro)palladium(II) [Pd(dppe)Cl2] and bis(dibenzylideneacetone)palladium(0) [Pd(dba)2], were used in combination with MeONa a remarkable activity was also obtained, independently of the oxidation state of the palladium precursor. During the reaction deposition of a solid was observed and recycle experiments carried out both on the recovered solid and on the liquid phase suggested that also in this case the activity has to be addressed to both heterogeneous and homogeneous (or colloidal) palladium species.

An enantioselective and branch-regioselective alpha-allylation of N-methyl anilines under dual palladium/photoredox catalysis is described. Readily available N-methyl anilines are used as formal “hard” alkyl nucleophiles without preactivation. Acetic acid is the only side product, which leads to a high atom economy of this reaction. This protocol shows good functional group tolerance and broad scope. A range of chiral homoallylic amines were prepared in moderate to good yields (up to 76%) and excellent regioselectivities (B:L > 95:5 in all cases) and enantioselectivities (up to 96% ee) under mild reaction conditions.

N-Arylamido complexes of zirconium in which the amido functional group is attached to an o-(alkyliminoethyl) substituted aromatic ring, have been synthesised by salt elimination reactions and characterised by spectroscopic and diffraction methods; they are analogous to the N-silylamido species recently reported (Dalton Trans., 2002, 3290-3299). The ligands 2-[CyN=C(CH 3)]C6H4N(H)(xyl), LxylH, and 2-[CyN=C(CH3)]C6H4N(H)(mes) LmesH, Cy – C6H11, xyl = 3,5-Me2C6H 3 mes = 2,4,6-Me3C6H2, were prepared in good yields by Buchwald-Hartwig amination of the arylbromides with 2-[CyN=C(CH3)]C6H4NH2. Reaction of LmesLi with Zr(NEt2)2Cl2(thf) 2 gave after chloride substitution the arylamido ketimino complex LmesZr(NEt2)2Cl 1; variable amounts of the arylamido vinylamido complex 2 were also obtained. Interaction of L mesLi or LxylLi with Ti(NMe2) 2Cl2 gave rise to the tripodal bis-amido amino complexes 5 and 6 possibly formed by ligand rearrangement involving migration of the dimethylamido group to the ketimino carbon.

The bis(diphenylphisphino)ferrocene (dppf) derived palladium analogue of [PdCl2(dppf)] on reaction with the sodium salt of pyridyl/pyrimidyl selenolate yielded mononuclear cis configured complex [Pd(SeAr)2(dppf)] (Ar = C5H4N, C4H(4,6-Me)2N2), as did the platinum precursor [PtCl2(dppf)] with methyl substituted pyrimidyl salt giving [Pt{SeC4H(4,6-Me)2N2}2(dppf)]. In contrast, the reaction of platinum precursor with the sodium salt of pyridylselenolate gave two different complexes [Pt2(mu-SeC5H4N)2(dppf)2]2+ and [Pt(Cl)(SeC5H4N)(dppf)] depending in the reaction solvent. These complexes were characterized by elemental analysis and NMR (1H, 31P) spectroscopy. The molecular structure of [Pt{SeC4H(4,6-Me)2N2}2(dppf)] was established by single crystal X-ray diffraction analysis.

Inspired by the proclivity of various palladium sources to form nanoparticles in imidazolium-based ionic liquids, we now report that tris-imidazolium salts bearing hexadecyl chains and a bridging mesitylene moiety are potent stabilizers of palladium nanoparticles efficiently prepared via a Chaudret-type hydrogenation of the bis(dibenzylideneacetone)palladium(0). The palladium nanoparticles have been isolated in pure form and characterized by 1H nuclear magnetic resonance, transmission electron microscopy, electron diffraction and dynamic light scattering. The new materials proved effective in Suzuki cross-coupling at a loading of 0.2% palladium. Thus, using a tris-imidazolium iodide-palladium material, a series of biaryl products has been prepared starting from aryl bromides and some activated chlorides. The possibility that this catalytic activity might be due to the formation of palladium N-heterocyclic carbenes has been addressed through solid state 13C NMR and the synthesis of an imidazolium analogue in which the acidic 2-H was replaced with a methyl group.

A palladium-catalyzed protocol for the first direct diarylation of 6,7-benzindoles with aryl iodides at the C4 and C5 positions was developed. The key to this strategy was the employment of pivaloyl as the directing group at the C3 position and the blocking effect at the C6 and C7 positions. The reaction proceeded very well, providing a series of diarylated 6,7-benzindoles without prefunctionalization at the reactive sites. Several examples on the unexpected monoarylation of 6,7-benzindoles at the C5 position were also presented.

UV irradiation of Pd(PtBu3)2 in n-hexane or THF gives the diamagnetic dinuclear complex 2, 2-methylpropene, and hydrogen.The complex was also obtained from the reaction of Pd(eta5-C5H5)(eta3-C3H5) with PtBu2H in toluene.Its crystal and molecular structure were determined by an X-ray diffraction study.Each Pd bears a terminal PtBu2H ligand and the two metal centers are bridged by two phosphido ligands.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Recommanded Product: 53199-31-8, you can also check out more blogs about53199-31-8
