Synthetic Route of 72287-26-4, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Article, and a compound is mentioned, 72287-26-4, [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II), introducing its new discovery.

Diarylmethine-containing stereocenters are present in pharmaceuticals and natural products, making the synthetic methods that form these chiral centers are important in industry. We have applied iridium complexes with novel N,P-chelating ligands to the asymmetric hydrogenation of trisubstituted olefins, forming diarylmethine chiral centers in high conversions and excellent enantioselectivities (up to 99% ee) for a broad range of substrates. Our results support the hypothesis that steric hindrance in one specific area of the catalyst is playing a key role in stereoselection, as the hydrogenation of substrates differing little at the prochiral carbon occurred with high enantioselectivity. As a result, excellent stereodiscrimination was obtained even when the prochiral carbon bore, for example, phenyl and p-tolyl groups.

The two nitroolefins, (Z)-1-(3-nitrophenyl)-4-phenylbut-1-ene and (Z)-1-(3-nitrophenyl)-5-phenylpent-1-ene, were stereospecifically prepared by Pd(0)-catalyzed cross-coupling reaction between (Z)-beta-bromo-3-nitrostyrene and 2-phenylethyl- or 3-phenylpropyl zinc chloride, respectively. The yield reached 60% in spite of the well-known tendency of aralkyl organometallic halides to undergo beta-elimination during the catalytic reaction. Only Pd-complexes displayed a satisfactory catalytic activity, the presence of the nitro group destroying that of related Ni-derivatives. 2002 Elsevier Science B.V. All rights reserved.

By what means and how well can axial chirality be controlled in an intermolecular Suzuki biaryl cross-coupling reaction? The directionality of reductive elimination [Eq.(1)] is completely controlled by using a strategically positioned internal ligand L to afford a single biaryl atropisomer corresponding to the korupensamine A skeleton.

The consecutive syntheses of imidazoles 1-(4-X-C6H 4)-4,5-R2-cC3HN2 (3a, X = Br, R = H; 3b, X = I, R = Me; 3c, X = H, R = Me; 5, X = Fc, R = H; 7, X = CCFc, R = H; 9, X = C6H5, R = Me; Fc = Fe(eta5- C5H4)(eta5-C5H5)), phosphino imidazoles 1-(4-X-C6H4)-2-PR?2- 4,5-R2-cC3N2 (11a-k; X = Br, I, Fc, FcCC, Ph; R = H, Me; R? = Ph, cC6H11, cC4H3O), imidazolium salts [1-(4-X-C 6H4)-3-R??-4,5-R2- cC3HN2]I (16a; X = Br, R = H, R?? = n-Bu; 16b, X = Br, R = H, R?? = n-C8H17; 16c, X = I, R = Me, R?? = n-C8H17, 16d, X = H, R = Me, R?? = n-C8H17) and phosphino imidazolium salts [1-C6H5-2-PR?2-3-n-C 8H17-4,5-Me2-cC3N 2]PF6 (17a, R? = C6H5; 17b, R? = cC6H11) or [1-(4-P(C 6H5)2-C6H4)-3-n-C 8H17-4,5-Me2-cC3HN 2]PF6, (20) and their selenium derivatives 1-(4-X-C 6H4)-2-P(Se)R?2-4,5-R2- cC3N2 (11a-Se-f-Se; X = Br, I; R = H, Me; R? = C6H5, cC6H11, cC4H3O) are reported. The structures of 11a-Se and [(1-(4-Br-C6H4)-cC3H 2N2-3-n-Bu)2PdI2] (19) in the solid state were determined. Cyclovoltammetric measurements were performed with the ferrocenyl-containing molecules 5 and 7 showing reversible redox events at E0 = 0.108 V (DeltaEp = 0.114 V) (5) and E0 = 0.183 V (DeltaEp = 0.102 V) (7) indicating that 7 is more difficult to oxidise. Imidazole oxidation does not occur up to 1.3 V in dichloromethane using [(n-Bu)4N][B(C6F5) 4] as supporting electrolyte, whereas an irreversible reduction is observed between -1.2 – 1.5 V. The phosphino imidazoles 11a-k and the imidazolium salts 17a,b and 20, respectively, were applied in the Suzuki C-C cross-coupling of 2-bromo toluene with phenylboronic acid applying [Pd(OAc) 2] as palladium source. Depending on the electronic character of 11a-k, 17a,b and 20 the catalytic performance of the in situ generated catalytic active species can be predicted. As assumed, more electron-rich phosphines with their higher donor capability show higher activity and productivity. Additionally, 11e was applied in the coupling of 4-chloro toluene with phenylboronic acid showing an excellent catalytic performance when compared to catalysts used by Fu, Beller and Buchwald. Furthermore, 11e is eligible for the synthesis of sterically hindered biaryls under mild reaction conditions. C-C Coupling reactions with the phosphino imidazolium salts 17b and 20 in ionic liquids [BMIM][PF6] and [BDMIM][BF4] were performed, showing less activity than in common organic solvents.

Two-photon microscopy is a powerful tool for studying biological systems. In search of novel two-photon absorbing dyes for bioimaging, we synthesized a new anthracene-based dipolar dye (anthradan) and evaluated its two-photon absorbing and imaging properties. The new anthradan, 9,10-bis(o-dimethoxy-phenyl)-anthradan, absorbs and emits at longer wavelengths than acedan, a well-known two-photon absorbing dye. It is also stable under two-photon excitation conditions and biocompatible, and thus used for two-photon imaging of mouse organ tissues to show bright, near-red fluorescence along with negligible autofluorescence. Such an anthradan thus holds promise as a new class of two-photon absorbing dyes for the development of fluorescent probes and tags for biological systems.

The reaction of 1-alkynes, CO, and methanol (hydroesterification) catalyzed by palladium-phosphine complexes has been studied in acetonitrile media. Branched alpha,beta-unsaturated ester was mainly produced in the presence of a catalytic amount of a palladium complex containing PPh3. In contrast, dppf-based palladium complexes showed excellent regioselectivity for the formation of linear alpha,beta-unsaturated ester. On the other hand, hydroesterification of 1,7-octadiyne with a catalyst system of Pd(OAc)2/PPh3/TsOH followed a different path to give a cyclized carbonylation product aS the major product. A tentative mechanism involving a PdH species has been proposed for these reactions. (C) 2000 Elsevier Science B.V.

A novel palladium-catalyzed cascade cyclization of alkene-tethered aryl halides with o-bromobenzoic acids is described, which provides an efficient avenue for building various fused hexacyclic scaffolds containing indolo[2,1-a]isoquinoline in moderate to excellent yield. The method enables the construction of three C-C bonds through an intramolecular carbopalladation, C-H activation, and a decarboxylation sequence. Furthermore, dihydrocyclohepta[de]naphthalene-fused indolo[2,1-a]isoquinolines can be synthesized in moderate yield by constructing a seven-membered ring.
