17078-29-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 17078-29-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,7,0,7 and 8 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 17078-29:
(7*1)+(6*7)+(5*0)+(4*7)+(3*8)+(2*2)+(1*9)=114
114 % 10 = 4
So 17078-29-4 is a valid CAS Registry Number.

Copper-Catalyzed Ullmann-Type Coupling and Decarboxylation Cascade of Arylhalides with Malonates to Access α-Aryl Esters

Cheng, Fei,Chen, Tao,Huang, Yin-Qiu,Li, Jia-Wei,Zhou, Chen,Xiao, Xiao,Chen, Fen-Er

supporting information, p. 115 - 120 (2022/01/04)

We have developed a high-efficiency and practical Cu-catalyzed cross-coupling to directly construct versatile α-aryl-esters by utilizing readily available aryl bromides (or chlorides) and malonates. These gram-scale approaches occur with turnovers of up to 1560 and are smoothly conducted by the usage of a low catalyst loading, a new available ligand, and a green solvent. A variety of functional groups are tolerated, and the application occurs with α-aryl-esters to access nonsteroidal anti-inflammatory drugs (NSAIDs) on the gram scale.

Pd-catalyzed decarboxylative cross-couplings of potassium malonate monoesters with aryl halides

Feng, Yi-Si,Wu, Wei,Xu, Zhong-Qiu,Li, Yan,Li, Ming,Xu, Hua-Jian

experimental part, p. 2113 - 2120 (2012/03/26)

An efficient catalytic protocol for Pd-catalyzed decarboxylative cross-coupling of potassium malonate monoesters and derivatives with aryl bromides and chlorides are described. Because of its broad applicability, this new catalytic system provides an alternative method for the preparation of diverse aryl acetic acids and derivatives.

Practical synthesis of 2-arylacetic acid esters via palladium-catalyzed dealkoxycarbonylative coupling of malonates with aryl halides

Song, Bingrui,Rudolphi, Felix,Himmler, Thomas,Goossen, Lukas J.

supporting information; experimental part, p. 1565 - 1574 (2011/08/03)

A new palladium-based system was developed that catalyzes the coupling of aryl halides with diethyl malonates in the presence of mild bases. In the course of the reaction, the intermediately formed diethyl arylmalonate is directly converted into the arylacetic acid ester via liberation of carbon dioxide and an alkanol. This cross-coupling/dealkoxycarbonylation process provides an efficient and high-yielding synthetic entry to diversely functionalized arylacetic acid esters. Two complementary protocols were developed, one of which is optimal for electron-rich, the other for electron-poor aryl halides. Both make use of low loadings of palladium(0) bis(dibenzylideneacetone) (0.5 mol%)/tri-tert-butylphosphonium tetrafluoroborate (1.1 mol%) as the catalyst and diethyl malonate as the reaction solvent. The new procedures are particularly effective for sterically hindered substrates. Copyright
