Basavaraj, M.; Giles, D.; Das, A. K.; Sakharam, A. G. published an article in 2018, the title of the article was Synthesis and characterization of some novel indolizine derivatives.Quality Control of Ethyl indolizine-1-carboxylate And the article contains the following content:

A novel approach was adopted for the synthesis of Indolizine nucleus. Pyridinium-N-methylides were synthesized by reacting pyridine with different haloacetic acids. Further, the indolizine nucleus were synthesized through 1,3-cycloaddition of pyridinium-N-methylides with electron deficient alkynes or alkenes in presence of MnO2 to give indolizine carboxylates. Later on, derivatives of indolizine were prepared by treating indolizine carboxylates with hydralazine and metformin. Synthesis of indolizine 2-carboxylic acid was achieved, by reacting 2-Me pyridine with Et bromopyruvate. The resulting acid was treated with hydralazine and metformin to form corresponding indolizine derivatives Synthesized compounds were characterized by IR and NMR spectroscopic techniques. The experimental process involved the reaction of Ethyl indolizine-1-carboxylate(cas: 93476-46-1).Quality Control of Ethyl indolizine-1-carboxylate

Xu, Xiao-Feng; Wang, Yao-Feng; Guo, Tao; Luan, Li-Kun; Liu, Shan-Shan; Xu, Bao-Hua published an article in 2022, the title of the article was Synthesis of adiponitrile from dimethyl adipate and ammonia in the vapor-phase over niobium oxide.Formula: C7H10O3 And the article contains the following content:

An environmentally benign route leading to adiponitrile (ADN), a nylon-6,6 intermediate, was achieved by direct vapor-phase nitrilation of di-Me adipate (DMA) with ammonia (NH3) in a fixed-bed reactor. The challenges of this reaction include not only inhibiting both intramol. cyclization and the intermol. polycondensation of the electron-withdrawing group functionalized carbon chain but also suppressing the thermolysis of aliphatic DMA and ADN. Both amphoteric oxides and acidic oxides enable the transformation but exhibit different reactivities. Under evaluation conditions, the acidic oxides exhibit moderate to good nitrile selectivity, while the amphoteric oxides exhibit high DMA conversions with relatively low nitrile selectivity. Under the optimized conditions, the desired ADN was obtained with a selectivity of 84.3% with 97.7% DMA conversion over Nb2O5-1000 consisting of a monoclinic structure/phase (H-Nb2O5). The structure-performance relationship of this catalyst was preliminarily discussed. Furthermore, a tentative reaction pathway consisting of ammonolysis and dehydration processes in a tandem mode was proposed. The experimental process involved the reaction of Methyl 2-cyclopentanonecarboxylate(cas: 10472-24-9).Formula: C7H10O3

On February 28, 2021, Bukowska, Agnieszka; Bester, Karol; Pytel, Maciej; Bukowski, Wiktor published an article.Application of 2358-84-1 The title of the article was Polymer Beads Decorated with Dendritic Systems as Supports for A3 Coupling Catalysts. And the article contained the following:

The gel type microscopic polymer beads bearing epoxy functionalities were modified using the two-stage procedures in order to decorate their surface with the moieties of the zeroth order PAMAM type dendrimer and different heterocyclic aldehydes (2-pyridinecarboxaldehyde, 2-pyrrolidinecarboxaldehyde, furfural or 2-thiophenecarboxaldehyde). The polymeric supports provided in this manner were then used for the immobilization of copper(II) ions. The resulting materials were characterized using different instrumental techniques (optical microscopy, SEM, FTIR microscopy, DR UV-Vis, ICP-OES, and thermal anal.). They were also used as catalysts in the model A3 coupling reaction of benzaldehyde, morpholine and phenylacetylene. The best catalytic activity was found for the polymeric catalyst bearing 2-pyridinecarboxaldehyde moieties. It turned out to be effective in the A3 coupling reactions included different benzaldehyde, alkyne, and secondary amine derivatives, as well. It could also be recycled several times without a significant decrease in its activity in the model A3 coupling reaction. The experimental process involved the reaction of Oxybis(ethane-2,1-diyl) bis(2-methylacrylate)(cas: 2358-84-1).Application of 2358-84-1
