Highly active but sterically demanding: Ambient-temperature Suzuki cross-coupling of aryl chlorides is possible with a palladium(o) complex bearing two bulky, N-heterocyclic carbene ligands (see structure). Nearly quantitative yields are obtained within two hours with some reagents, which makes this compound the most active catalyst known to date under these conditions.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 69861-71-8 is helpful to your research. Reference of 69861-71-8

The intermolecular alpha-arylation and vinylation of amides by palladium-catalyzed coupling of aryl bromides and vinyl bromides with zinc enolates of amides is reported. Reactions of three different types of zinc enolates have been developed. The reactions of aryl halides occur in high yields with isolated Reformatsky reagents generated from alpha-bromo amides, with Reformatsky reagents generated in situ from alpha-bromo amides, and with zinc enolates generated by quenching lithium enolates of amides with zinc chloride. This use of zinc enolates, instead of alkali metal enolates, greatly expands the scope of amide arylation. The reactions occur at room temperature or 70 C with bromoarenes containing cyano, nitro, ester, keto, fluoro, hydroxyl, or amino functionality and with bromopyridines. Moreover, the reaction has been developed with morpholine amides, the products of which are precursors to ketones and aldehydes. The arylation of zinc enolates of amides was conducted with catalysts bearing the hindered pentaphenylferrocenyl di-tert-butylphosphine (Q-phos) or the highly reactive, dimeric, Pd(I) complex {[P(t-Bu) 3]PdBr}2.

A palladium-catalyzed asymmetric decarboxylative allylic alkylation of allyl 2,2-diphenylglycinate imines using (S,S)-f-binaphane as a chiral supporting ligand has been developed. This transformation allows for decarboxylative generation and enantioselective allylation of nonenolate alpha-imino (2-azaallyl anions) to afford alpha-aryl homoallylic imines.

Described herein is the first total chemical synthesis of the unique alpha-subunit of the human glycoprotein hormone (alpha-hGPH). Unlike the biologically derived glycoprotein hormones, which are isolated as highly complex mixtures of glycoforms, alpha-hGPH obtained by chemical synthesis contains discrete homogeneous glycoforms. Two such systems have been prepared. One contains the disaccharide chitobiose at the natural N-glycosylation sites. The other contains dodecamer oligosaccharides at these same sites. The dodecamer sugar is a consensus sequence incorporating the key features associated with human glycoproteins.

Autophagy inducers represent new promising agents for the treatment of a wide range of medical illnesses. However, safe autophagy inducers for clinical applications are lacking. Inhibition of cdc2-like kinase 1 (CLK1) was recently found to efficiently induce autophagy. Unfortunately, most of the known CLK1 inhibitors have unsatisfactory selectivity. Herein, we report the discovery of a series of new CLK1 inhibitors containing the 1H-[1,2,3]triazolo[4,5-c]quinoline scaffold. Among them, compound 25 was the most potent and selective, with an IC50 value of 2 nM against CLK1. The crystal structure of CLK1 complexed with compound 25 was solved, and the potency and kinase selectivity of compound 25 were interpreted. Compound 25 was able to induce autophagy in in vitro assays and displayed significant hepatoprotective effects in the acetaminophen (APAP)-induced liver injury mouse model. Collectively, due to its potency and selectivity, compound 25 could be used as a chemical probe or agent in future mechanism-of-action or autophagy-related disease therapy studies.

Three-component coupling reaction of acid chlorides, organodisilanes, and 1,3-dienes achieves 1,4-carbosilylation of the 1,3-dienes to afford allylic silanes as the product. Bis(dibenzylideneacetone)palladium, a naked Pd(0) complex without donating ligand, showed high catalytic activity. A carbon and a silicon substituent are introduced at 1- and 4-positions of the 1,3-dienes regio- and stereoselectively with concomitant decarbonylation of the acid chlorides. A wide variety of allylic silanes are synthesized in high yields from these easily accessible substrates. On the other hand, a bulky acid chloride such as adamantane-1-carboxylic acid chloride did not undergo the decarbonylation reaction but afforded allylic silanes containing acyl functionality. In all these reactions, transmetalation of the disilanes with eta3-allylchloropalladium intermediates might be a critical step in the catalytic cycle. As a model reaction for the transmetalation, reaction of di-mu-chlorobis[(1,2,3-eta)-4-phenyl-2-butenyl]dipalladium with disilanes was carried out. Although intermediate eta3-allylsilylpalladium species could not be detected, the corresponding allylic silanes, silyl chlorides, and Pd(0) metal were formed during the reaction. Furthermore, a similar three-component coupling reaction using aryl iodides, organosilylstannanes, and dienes also proceeded. However, the selectivity and the yield decreased considerably.

The regioselective palladation reactions of 3-substituted derivatives of 2-<(dimethylamino)methyl>naphthalene, C10H6(CH2NMe2)-2-R-3 (R=Cl, SiMe3 or OSiMe3), were studied.For the substrate with R=Cl, no cyclopalladation at position 1 was observed and the co-ordination complex was isolated.The 3-palladated product was formed in 10percent yield via C-Cl activation.The reaction of 2-<(dimethylamino)methyl>-3-methylnaphthalene with Pd(O2CMe)2 and work-up with LiCl did lead to palladation at position 1, the resulting complex being isolated in 96percent yield.The crystal structure of bis(acetonitrile) <2-<(dimethylamino)methyl>-3-methyl-1-naphthyl>palladium trifluoromethanesulfonate was solved.Monoclinic, space group P21/n, with a=13.193(1), b=11.801(1), c=14.797(1) Angstroem, beta=105.15(1) deg, Z=4.The structure was refined to R=0.042 for 3455 reflections with I > 2.5?(I).Palladation at position 1 was also achieved by oxidative addition of 1-bromo-2-<(dimethylamino)methyl>naphthalene to (dba=dibenzylideneacetone).Protection of C(3) with R=SiMe3 resulted in quantitative replacement of the SiMe3 group by palladium.Silicon-oxygen bond cleavage was observed when the substrate with R=OSiMe3 was treated with Pd(O2CMe)2.Palladium bis<3-<(dimethylamino)methyl>-2-naphtholate> was obtained quantitatively.Oxidation of several arylpalladium complexes with tBuO2H was achieved in the presence of (acac=acetylacetonate) or <2> (cod=cycloocta-1,5-diene) as catalyst.The corresponding 1-naphthols were prepared in yields varying from 33 to 78 percent.In a number of cases the corresponding 1,4-naphthoquinones were prepared in yields varying from 18 to 38percent.

Dimethyl acetylenedicarboxylate reacts with PdI(C6H3Me2-3,5)(bpy) in the presence of AgBF4, causing rapid insertion of three acetylene molecules into the Pd-C bond to afford [Pd{C(CCOOMe-CZ-CZ-CZ=CZ)(Z)(C6H3Me 2-3,5)}(bpy)]BF4 (Z = COOMe), whereas a similar reaction without AgBF4 gives the product of a single insertion of the carbon-carbon triple bond, Pd(I)(CZ=CZC6H3Me2-3,5)(bpy).
