General Description

The electrocarboxylation of 2,2-dimethylpropiophenone has been carried out in N-methyl-2-pyrrolidone in a diaphragmless cell equipped with a carbon cathode and an aluminium sacrificial anode.

Check Digit Verification of cas no

The CAS Registry Mumber 938-16-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,3 and 8 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 938-16:
(5*9)+(4*3)+(3*8)+(2*1)+(1*6)=89
89 % 10 = 9
So 938-16-9 is a valid CAS Registry Number.

Rhodium-Catalyzed and Chiral Zinc Carboxylate-Assisted Allenylation of Benzamides via Kinetic Resolution

Mao, Ruxia,Zhao, Yanliang,Zhu, Xiaohan,Wang, Fen,Deng, Wei-Qiao,Li, Xingwei

supporting information, p. 7038 - 7043 (2021/09/18)

Enantioenriched allenes are important building blocks. While they have been accessed by other coupling methodologies, enantioenriched allenes have been rarely obtained via C-H activation. In this work, kinetic resolution of tertiary propargyl alcohols as an allenylating reagent has been realized via rhodium(III)-catalyzed C-H allenylation of benzamides. The reaction proceeded efficiently under mild conditions, and both the allenylated products and the propargyl alcohols were obtained in high enantioselectivities with an s-factor of up to 139. The resolution results from bias of the two propargylic substituents and is assisted by a chiral zinc carboxylate additive.

Mild oxidation of benzyl alcohols to benzyl aldehydes or ketones catalyzed by visible light

Cheng, Dongping,Li, Xiaonian,Ren, Shujian,Xu, Xiaoliang

supporting information, (2021/07/02)

Induced by visible light, mild oxidation condition to prepare benzyl aldehydes or ketones have been developed by using bromotrichloromethane as photochemical oxidant. This method avoids high temperature, pressure and peroxidation with only visible light as the green driving force.
