On July 13, 1999, Cheng, Jianjun; Deming, Timothy J. published an article.COA of Formula: C10H12N2O The title of the article was Screening of Optically Active Nickel Initiators for Enantioasymmetric Polymerization of γ-Benzyl Glutamate-N-Carboxyanhydride. And the article contained the following:

The use of chiral pyridinyl oxazoline ligands in nickel initiators to enantioasym. polymerize γ-benzyl glutamate N-carboxyanhydride (I) was studied. Catalysts prepared from 4,4-dimethyl-(2-pyridinyl)-2-oxazoline and Ni(COD) displayed I polymerization activity which was virtually identical to that of bipyridine-Ni(COD). The kinetic selectivity for the D-antipode displayed by catalyst prepared from (4S)-4-tert-butyl-(2-pyridinyl)-2-oxazoline in homopolymerization was also displayed in polymerization of the racemate. The selectivity of the catalysts was highly sensitive to substitution on the 4 position of the oxazoline ring. The experimental process involved the reaction of 2-(4,5-Dihydro-4,4-dimethyl-2-oxazolyl)pyridine(cas: 109660-12-0).COA of Formula: C10H12N2O

On March 14, 2005, Munoz, M. Paz; Adrio, Javier; Carretero, Juan Carlos; Echavarren, Antonio M. published an article.Recommanded Product: 109660-12-0 The title of the article was Ligand Effects in Gold- and Platinum-Catalyzed Cyclization of Enynes: Chiral Gold Complexes for Enantioselective Alkoxycyclization. And the article contained the following:

Phosphine and bidentate N-N ligands inhibit the Alder-ene-type cycloisomerization of enynes catalyzed by Pt(II) and favor the alkoxycyclization process. The enantioselective Pt(II)-catalyzed alkoxycyclization has been studied in the presence of chiral mono- and bidentate phosphines, as well as chiral bidentate N-N ligands. Modest levels of enantioselection (up to 50% ee) have been obtained with Tol-BINAP as ligand. The alkoxycyclizations with a catalyst formed from [Au(L)Cl]/AgX proceed more readily, and up to 94% ee’s have been obtained using [(AuCl)2(Tol-BINAP)] (1) as the precatalyst. X-ray crystal structures of Au(I) complexes 1 and chloro-(R)-2-(tert-butylsulfenyl)-1-(diphenylphosphino)ferrocene gold(I) show the AuCl fragments monocoordinated with the P centers of the chiral phosphine ligands.

A com. available macroreticular resin containing 73 mol % 4-vinylpyridine crosslinked with 21 mol % divinylbenzene (I) was successfully derivatized at the pyridine rings by a multi-step synthetic pathway. First-time application of reactions well established for monomeric pyridine derivatives (N-oxidation, Reissert-Henze cyanation, and 2-oxazoline formation) to a copolymer of 4-vinylpyridine furnished the new functionalized resins, I-4-vinyl-2-(4,4-dimethyl-2-oxazolinyl)pyridine copolymer (II) and I-4-vinyl-2-pyridinecarboxylic acid copolymer (III) in yields for functionalization of pyridine residues of 58% in each case. Estimates of formation constants for 1:1 complexes of Cu(II) and Ni(II) ions with the oxazolinylpyridine and 2-pyridinecarboxylate residues of the new resins were obtained with a competitive spectrophotometric method. The formation constants for the Cu(II)- and Ni(II)-II complexes were 107.7 M-1 for Cu(II) and 105.8 M-1 for Ni(II). The formation constants for the Cu(II) and Ni(II) complexes with III were 108.8 and 105.5 M-1, resp.

On April 2, 2021, Lu, Dengfu; Cui, Jiajia; Yang, Sen; Gong, Yuefa published an article.Category: pyridine-derivatives The title of the article was Iron-catalyzed cyanoalkylation of glycine derivatives promoted by pyridine-oxazoline ligands. And the article contained the following:

An iron-catalyzed C(sp3)-H cyanoalkylation of glycine derivatives with cyclobutanone oxime esters was established for the incorporation of a cyano group into amino acids and peptides. In this reaction, Fe(NTf2)2 and pyridine-oxazoline ligands form highly active catalysts that could simultaneously and selectively activate both substrates. Preliminary mechanistic studies revealed the excellent chemo-selectivity may stem from an in situ formed imine intermediate and a consecutive radical addition The evidence suggested the interaction between glycinate substrate and the Fe-catalyst has a prominent impact on the catalytic activity, and the catalyst may also activate the imine intermediate as a Lewis acid. The experimental process involved the reaction of 2-(4,5-Dihydro-4,4-dimethyl-2-oxazolyl)pyridine(cas: 109660-12-0).Category: pyridine-derivatives

Half-sandwich complexes [RhCl(pymox)Cp*][SbF6] (1-7) (pymox = pyridyloxazoline) were synthesized as single diastereomers.

Treatment of the dication [Rh(OH2)(iPr-pymox)Cp*]2+ with [X]- gives [RhX(iPr-pymox)Cp*][SbF6] (X = Br, I) as single diastereomers while reaction with 4-Mepy (4-methylpyridine) gives [Rh(4-Mepy)(iPr-pymox)Cp*][SbF6] as a mixture of diastereomers. Two complexes, [RhCl(iPr-pymox)Cp*][SbF6] (3) and [RhCl(Bz-pymox)Cp*][SbF6] (6) were characterized by x-ray crystallog.
