294878-57-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 294878-57-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,9,4,8,7 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 294878-57:
(8*2)+(7*9)+(6*4)+(5*8)+(4*7)+(3*8)+(2*5)+(1*7)=212
212 % 10 = 2
So 294878-57-2 is a valid CAS Registry Number.

Palladium(II)-catalyzed Intermolecular Cascade Cyclization of Methylenecyclopropanes with Aromatic Alkynes: Construction of Spirocyclic Compounds Containing Indene and 1,2-Dihydronaphthalene Moieties

Fang, Wei,Wei, Yin,Shi, Min

, (2019/05/22)

A palladium(II)-catalyzed intermolecular cascade cyclization of methylenecyclopropanes with aromatic alkynes is reported in this paper. The reaction involves a migratory insertion of alkyne, an intramolecular Heck-type reaction, and β-H elimination, providing a series of spirocyclic compounds containing indene and 1,2-dihydronaphthalene moieties in moderate to excellent yields upon heating.

Synthesis of Substituted Naphthalenes by 1,4-Palladium Migration Involved Annulation with Internal Alkynes

Wei, Dong,Hu, Tian-Jiao,Feng, Chen-Guo,Lin, Guo-Qiang

, p. 743 - 748 (2018/07/25)

The palladium catalyzed annulation of 1-bromo-2-vinylbenzene derivatives with internal alkynes was realized for the efficient synthesis of substituted naphthalenes. A controllable aryl to vinylic 1,4-palladium migration process is the key for success.

Palladium Catalyzed Carbonylative Coupling for Synthesis of Arylketones and Arylesters Using Chloroform as the Carbon Monoxide Source

Sharma, Poonam,Rohilla, Sandeep,Jain, Nidhi

, p. 1105 - 1113 (2018/06/18)

We describe a modular, palladium catalyzed synthesis of aryl(hetero)aryl benzophenones and aryl benzoates from aryl(hetero)aryl halides using CHCl3 as the carbonyl source in the presence of KOH. The reaction occurs in tandem through an initial carbonylation to generate an aroyl halide, which undergoes coupling with arylboronic acids, bornonates, and phenols. Direct carbonylative coupling of indoles at the third position has also been accomplished under slightly modified reaction conditions by in situ activation of the C-H bond. Notably, CHCl3 is a convenient and safe alternation of CO gas, provides milder reaction conditions with high functional group tolerance, and gives the products in moderate to good yields.

Method for synthesizing axial chiral biaryl compounds by utilizing tertiary amine small organic molecules

-

, (2017/05/02)

The invention discloses a method for synthesizing axial chiral biaryl compounds by utilizing tertiary amine small organic molecules. According to the method, similar Mortia-Baylis-Hillman reactions in molecules are utilized, and chiral prosthetic groups are used as inducing groups, so that axial chiral biaryl compounds are asymmetrically constructed in one step. The method for synthesizing the axial chiral biaryl compounds has the advantages of environmental friendliness, no use of expensive metal catalysts, atom economy and easiness in modification of substrates, the yield of the biaryl compounds as products can reach 80% to 97%, and a De value reaches 70% to 80%. The invention provides a green environment-friendly way for various preparations of the axial chiral biaryl compounds.

Borylation of Olefin C-H Bond via Aryl to Vinyl Palladium 1,4-Migration

Hu, Tian-Jiao,Zhang, Ge,Chen, Ya-Heng,Feng, Chen-Guo,Lin, Guo-Qiang

, p. 2897 - 2900 (2016/03/19)

The aryl to vinyl palladium 1,4-migration was realized for the first time. The generated alkenyl palladium species was trapped by diboron reagents under Miyaura borylation conditions, providing a new method to synthesize β,β-disubstituted vinylboronates. The excellent regioselectivity and broad substrate scope were observed for this novel transformation.

Erbium trifluoromethanesulfonate catalyzed Friedel-Crafts acylation using aromatic carboxylic acids as acylating agents under monomode-microwave irradiation

Tran, Phuong Hoang,Hansen, Poul Erik,Nguyen, Hai Truong,Le, Thach Ngoc

, p. 612 - 618 (2015/02/19)

Erbium trifluoromethanesulfonate is found to be a good catalyst for the Friedel-Crafts acylation of arenes containing electron-donating substituents using aromatic carboxylic acids as the acylating agents under microwave irradiation. An effective, rapid and waste-free method allows the preparation of a wide range of aryl ketones in good yields and in short reaction times with minimum amounts of waste.

Palladium-phosphinous acid-catalyzed cross-coupling of aryl and acyl halides with aryl-, alkyl-, and vinylzinc reagents

Xu, Hanhui,Ekoue-Kovi, Kekeli,Wolf, Christian

, p. 7638 - 7650 (2008/12/22)

(Chemical Equation Presented) Several palladium-phosphinous acids have been prepared and employed in cross-coupling reactions of aryl or acyl halides with aliphatic and aromatic organozinc reagents. The POPd7-catalyzed reaction of aryl halides, including electron-rich aryl chlorides, and arylzinc reagents was found to afford biaryls exhibiting alkoxy, alkylthio, amino, ketone, cyano, nitro, ester, and heteroaryl groups in 75-93% yield. Excellent results were obtained with sterically hindered substrates which gave di- and tri-ortho-substituted biaryls in up to 92% yield. Aryl halides also undergo POPd7-catalyzed aryl-vinyl and aryl-alkyl bond formation under mild conditions. Styrenes and alkylarenes were prepared in 79-93% yield from aryl halides and vinyl or alkylzinc reagents. The replacement of aryl halides by acyl halides provides access to ketones which were produced in up to 98% yield when POPd was used as catalyst. This approach overcomes the limited substrate scope, reduced regiocontrol, and low functional group tolerance of traditional Friedel-Crafts acylation methods.
