The reaction of monosubstituted alkenes with 0.5 molar equiv of EtZn in the presence of a catalyst generated in situ by treatment ofClzZrCpz with 2 molar equiv of EtMgBr produces regioselectively the corresponding diisoalkylzincs 1, generally in high yields. Their direct cross coupling with a variety of organic halides in the same reaction vessel can be achieved in good yields with a catalytic amount of a palladium complex.

Application of 95464-05-4, The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.95464-05-4, Name is 1,1′-Bis(diphenylphosphino)ferrocene-palladium(II)dichloride dichloromethane complex, molecular formula is C35H32Cl4FeP2Pd.

Homocoupling of naphthyl triflates 27, 16, 17 to the respective binaphthyls 28, 31 and 35 has been achieved in a one-pot procedure using bis(pinacolato)diboron and PdCl2(dppf). Use of potassium acetate as the base provides access to the initial naphthylboronate intermediates whereas the stronger base potassium phosphate is required in order to promote subsequent coupling of the naphthylboronate with a second equivalent of the naphthyl triflate. Attempts to convert binaphthyl 35 into bis-acetylnaphthalene 14, a key intermediate for the synthesis of the dimeric pyranonaphthoquinone antibiotic crisamicin A 2, via double Fries rearrangement of bis-acetate 37 derived from binaphthyl 35, were unsuccessful. Attempts to introduce the acetyl groups at C-7 and C-7? on bis-acetylnaphthalene 14 via Fries rearrangement of the monomeric precursors 21 and 15, before effecting homocoupling to a biaryl were unsuccessful. Introduction of an acetyl group via initial bromination ortho to the hydroxyl group in naphthol 18, which bears an electron rich benzyl ether at C-7, was plagued by the formation of phenolic coupling product 42 and naphthoquinone 43. Bromination of naphthol 45, bearing a less electron rich triflate group at C-7, also afforded binaphthol 47 resulting from phenolic coupling as well as naphthoquinone 48 when using N-bromosuccinimide at low temperature.

Synthetic Route of 95464-05-4, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 95464-05-4, molcular formula is C35H32Cl4FeP2Pd, introducing its new discovery.

Catalytic C-phenylation of methyl acrylate to methyl cinnamate with the Ph4SbX complexes (X = F, Cl, Br, OH, OAc, O2CEt) in the presence of the palladium compounds PdCl2, Pd(OAc)2, Pd2(dba)3, Pd(Ph3P)2Cl2, and Pd(dppf)Cl2 (dba is dibenzylideneacetone and dppf is bis(diphenylphosphinoferrocene)) was studied in organic solvents (MeCN, THF, DMF, MeOH, and AcOH). The highest yield of methyl cinnamate (73% based on the starting organometallic compound) was obtained for the Ph4SbCl- PdCl2 (1:0.04) system in acetonitrile.

The synthesis of tris{5?-[methylbis(2-thienyl)silyl]2,2?- bithienyl-5-yl} methylsilane, a first-generation bithiophenesilane dendrimer, is described. The conditions of effective formation of methyltrithienylsilane were found; methyltris(5-bromo-2-thienyl)silane and a number of other monofunctional derivatives of methyltrithienylsilane were synthesized for the first time. The advantages and drawbacks of the Suzuki and Kumada reactions for the formation of bithienyl fragments in the synthesis of oligothienylsilane dendrimers are discussed.

The ability to tune the reactivity of palladium carbenes derived from diphenylketene, which is dependent on the oxidation state of the metal center, is presented. Competition experiments illustrated that Pd(O) catalysts favor direct C-H functionalization of terminal alkynes and that Pd(II) catalysts lead to cyclopropanation of strained alkenes. In addition, a PdCl2- catalyzed cyclopropane isomerization of diphenylcyclo-propanes and an unprecedented Pd(II)-catalyzed domino cyclopropanation/isomerization reaction are described.

Trans -selective monoarylation of 1,1-dibromo- and 1,1-dichloro-1-alkenes (1) can be achieved in >80% yields and in ?98-99% stereoselectivity with arylzinc bromides in the presence of a catalytic amount of Cl2Pd(DPEphos) or Cl2Pd(dppb), the former permitting cleaner and higher yielding reactions. Although THF is a generally satisfactory solvent, ether and toluene are superior to THF in some cases. The second substitution of (Z)-alpha-bromostyrenes (3) with alkylzincs in the presence of 2 mol% of Pd(t Bu3P)2 proceeds to give the corresponding 2 in >90% yields and in ?98-99% stereoselectivity. Although somewhat less satisfactory, the use of Cl2Pd(DPEphos) permits a one-pot tandem arylation-alkylation.

In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 95464-05-4, name is 1,1′-Bis(diphenylphosphino)ferrocene-palladium(II)dichloride dichloromethane complex, introducing its new discovery. name: 1,1′-Bis(diphenylphosphino)ferrocene-palladium(II)dichloride dichloromethane complex

The reactions between [Pd(P-P)(OTf)2] (where P-P = dppp or dppf) and two different bipyridyl ligands (L1 = 1,3-bis(4-pyridylmethyl) urea and L2 = 1,3- bis(pyridinylmethyl)benzenedicarboxamide) containing hydrogen-bonding units have been studied. The X-ray crystal structures of three of these assemblies have been solved showing them to be the [2 + 2] metallo-macrocycles [Pd(P-P)(Ln)]2(OTf) 4 [P-P = dppp, n = 1, (1); P-P = dppp, n = 2, (2); P-P = dppf, n = 1, (3)]. To confirm whether the dimeric assembly of one of these species (1) is retained in solution, several investigations have been carried out. 1H NMR studies in DMSO and high resolution ESI mass spectrometry have shown that 1 is in equilibrium with a larger [3 + 3] metallo-macrocycle. The equilibrium between these two species can be modified by changing the temperature, concentration or solvent. Also, addition of certain anions (e.g. [H2PO4]-) to the mixture shifts the equilibrium favoring the formation of the [2 + 2] metallo-macrocycle over the [3 + 3] (initially present in a larger proportion).
