Check Digit Verification of cas no

The CAS Registry Mumber 38469-83-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,4,6 and 9 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 38469-83:
(7*3)+(6*8)+(5*4)+(4*6)+(3*9)+(2*8)+(1*3)=159
159 % 10 = 9
So 38469-83-9 is a valid CAS Registry Number.

Reactivity of several deactivated 3-aminobenzo[b]thiophenes in the Buchwald-Hartwig C-N coupling. Scope and limitations

Queiroz, Maria-Jo?o R.P.,Calhelha, Ricardo C.,Kirsch, Gilbert

, p. 13000 - 13005 (2007)

Di(hetero)arylamines were prepared in moderate to high yields by Buchwald-Hartwig C-N coupling of bromobenzenes bearing electron-withdrawing groups and of a bromobiphenyl with several methyl 3-aminobenzo[b]thiophene-2-carboxylates, using the coupling cond

Conversions of aryl carboxylic acids into aryl nitriles using multiple types of Cu-mediated decarboxylative cyanation under aerobic conditions

Cai, Hu,Cao, Xihan,Fu, Zhengjiang,Guo, Shengmei,Wang, Shuiliang

supporting information, p. 8381 - 8385 (2020/11/05)

Here, we used malononitrile or AMBN as a cyanating agent to develop efficient and practical protocols for Cu-mediated decarboxylative cyanations, under aerobic conditions, of aryl carboxylic acids bearing nitro and methoxyl substituents at the ortho position as well as of heteroaromatic carboxylic acids. These protocols involved economical methods to synthesize value-added aryl nitriles from simple and inexpensive raw materials. Further diversification of the 2-nitrobenzonitrile product was performed to highlight the practicality of the protocols. This journal is

Method for synthesizing aryl cyanide by taking aryl carboxylic acid as raw material

-

Paragraph 0077-0079, (2020/08/22)

The invention discloses a method for synthesizing aryl cyanide by taking aryl carboxylic acid as a raw material, which is characterized in that aryl cyanide is synthesized by taking aryl carboxylic acid as a raw material, taking a combination of NH4X and N, N-dimethylformamide as a cyanide source and taking silver sulfate and copper acetate as catalysts under the action of acid and oxygen. Compared with a conventional aryl cyanide synthesis method, the method disclosed by the invention has the advantages that reaction raw materials (aryl carboxylic acid, NH4X and N, N-dimethylformamide) are cheap and easy to obtain, and the dosage of a metal catalyst is small; meanwhile, oxygen is used as an oxidizing agent, so that the method has the obvious advantages of small environmental pollution, good tolerance to various functional groups on an aromatic ring, high yield and the like; the method disclosed by the invention can be widely applied to synthesis of medicines, functional materials, natural products and other fields in the industry and academic circles.

An industrial preparation method for 4-methoxy-2-nitrobenzoic acid is disclosed. In the method, p-difluorobenzene is adopted as an initial raw material and subjected to nitration, ammonolysis, diazotization bromination, cyaniding, methoxylation and hydrolysis which are six steps to synthesize the 4-methoxy-2-nitrobenzoic acid. The 4-methoxy-2-nitrobenzoic acid obtained by the method is white powdered solid with purity being 98.5%, the raw material conversion ratio in each step is 100%, and the total yield of the whole process is 35.8%.

Ag/Cu-mediated decarboxylative cyanation of aryl carboxylic acids with K4Fe(CN)6 under aerobic conditions

Fu, Zhengjiang,Jiang, Ligao,Li, Zhaojie,Jiang, Yongqing,Cai, Hu

supporting information, p. 917 - 924 (2019/03/17)

A method for facile synthesis of aryl nitriles has been well established via Ag/Cu-mediated decarboxylative cyanation of benzoic acids with K4Fe(CN)6 under aerobic conditions. The approach of using readily accessible aryl carboxylic acids and green K4Fe(CN)6 as starting material provides a feasible alternative to previous cyanation protocols. Control experiments revealed the key role of Cu for the process and excluded the possibility of a radical mechanism for the transformation.

Simple strategies for decarboxylative functionalizations of electron-deficient benzoic acids via using Cu(I) as promoter and electron-rich ones by employing Pd(II) as catalyst under aerobic conditions have been established, which lead to smooth synthesis of aryl halides (-I, Br, and Cl) through the decarboxylative functionalization of benzoic acids with readily available halogen sources CuX (X = I, Br, Cl), and easy preparation of benzonitriles from decarboxylative cyanation of aryl carboxylic acids with nontoxic and low-cost K4Fe(CN)6 under an oxygen atmosphere for the first time.

Carbopalladation of nitriles: Synthesis of 2,3-diarylindenones and polycyclic aromatic ketones by the Pd-catalyzed annulation of alkynes and bicyclic alkenes by 2-iodoarenenitriles

Pletnev, Alexandre A.,Tian, Qingping,Larock, Richard C.

, p. 9276 - 9287 (2007/10/03)

2-Iodobenzonitrile, its derivatives, and various heterocyclic analogues undergo palladium(O)-catalyzed annulation onto diarylacetylenes or bicyclic alkenes to afford 2,3-diarylindenones and polycyclic aromatic ketones in very good to excellent yields. This reaction represents one of the first examples of the addition of an organopalladium moiety to the carbon-nitrogen triple bond of a nitrile. The reaction is compatible with a number of functional groups. A reaction mechanism, as well as a model accounting for the electronic effects of substituents on the aromatic ring of the nitrile, is proposed.
