83993-82-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 83993-82-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,9,9 and 3 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 83993-82:
(7*8)+(6*3)+(5*9)+(4*9)+(3*3)+(2*8)+(1*2)=182
182 % 10 = 2
So 83993-82-2 is a valid CAS Registry Number.

Pyridine Skeleton Synthesis Using Acetonitrile as C4N1 Units and Solvent

Bai, Chaolumen,Guo, Huifang,Liu, Xin,Liu, Dan,Sun, Zhaorigetu,Bao, Agula,Baiyin, Menghe,Muschin, Tegshi,Bao, Yong-Sheng

, p. 12664 - 12675 (2021/09/18)

The first [3 + 2 + 1] methodology for pyridine skeleton synthesis via cascade carbopalladation/cyclization of acetonitrile, arylboronic acids, and aldehydes was developed. This reaction proceeds via six step tandem reaction sequences involving the carbopalladation reaction of acetonitrile, a nucleophilic addition, a condensation, an intramolecular Michael addition, cyclization, and aromatization. Delightfully, both palladium acetate and supported palladium nanoparticles catalyzed this reaction with similar catalytic performance. The characterization results of the fresh and used supported palladium nanoparticle catalysts indicated that the reaction might be performed via a Pd(0)/Pd(II) catalytic cycle that began with Pd(0). Furthermore, the products showed good fluorescence characteristics. The green homogeneous/heterogenous catalytic methodologies pave a new way for constructing the pyridine skeleton.

Copper-catalyzed efficient access to 2,4,6-triphenyl pyridinesviaoxidative decarboxylative coupling of aryl acetic acids with oxime acetates

Convenient one-pot synthesis of 1,2,4-oxadiazoles and 2,4,6-triarylpyridines using graphene oxide (GO) as a metal-free catalyst: Importance of dual catalytic activity

Basak, Puja,Dey, Sourav,Ghosh, Pranab

, p. 32106 - 32118 (2021/12/02)

A convenient and efficient process for the synthesis of 3,5-disubstituted 1,2,4-oxadiazoles and 2,4,6-triarylpyridines has been described using an inexpensive, environmentally benign, metal-free heterogeneous carbocatalyst, graphene oxide (GO). GO plays a dual role of an oxidizing agent and solid acid catalyst for synthesizing 1,2,4-oxadiazoles and triarylpyridines. This dual catalytic activity of GO is due to the presence of oxygenated functional groups which are distributed on the nanosheets of graphene oxide. A broad scope of substrate applicability and good sustainability is offered in this developed protocol. The results of a few control experiments reveal a plausible mechanism and the role of GO as a catalyst was confirmed by FTIR, XRD, SEM, and HR-TEM analysis.

Application of salicylic acid as an eco-friendly and efficient catalyst for the synthesis of 2,4,6-triaryl pyridine, 2-amino-3-cyanopyridine, and polyhydroquinoline derivatives

Roozifar, Majid,Hazeri, Nourallah,Faroughi Niya, Homayoun

, p. 1117 - 1129 (2021/02/26)

In this study, three eco-friendly, efficient, and convenient protocols have been reported for one-pot synthesis of 2,4,6-triaryl pyridine, 2-amino-3-cyanopyridine, and polyhydroquinoline derivatives using salicylic acid as a catalyst under solvent-free condition. The reported protocols offer several significant advantages such as the application of a nontoxic, neutral, and cheap catalyst, environmentally friendly conditions, the easy isolation of products by filtering, short reaction times, simple methodology, and good yields.

Rekunge, Deelip S.,Kale, Ishwari A.,Chaturbhuj, Ganesh U.

, p. 2455 - 2462 (2018/09/13)

Abstract: A simple, efficient, and green method of preparation for the synthesis of highly substituted pyridines by multicomponent reaction of acetophenones, aldehydes, and ammonium acetate using activated Fuller’s earth as an effective and reusable heterogeneous catalyst is described. The advantages of the present protocol include simple procedure with an easy workup procedure, mild reaction conditions, and high yields of the products. The performance of this reaction under solvent-free conditions using heterogeneous catalysts, such as activated Fuller’s earth, could enhance its efficiency from an economic as well as ecological point of view.
