62135-66-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 62135-66-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,2,1,3 and 5 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 62135-66:
(7*6)+(6*2)+(5*1)+(4*3)+(3*5)+(2*6)+(1*6)=104
104 % 10 = 4
So 62135-66-4 is a valid CAS Registry Number.

Copper(I)-catalysed aerobic oxidative selective cleavage of C[sbnd]C bond with DMAP: Facile access to N-substituted benzamides

Ma, Haojie,Lu, Guoqiang,Han, Bo,Huang, Guosheng,Zhang, Yuqi,Wang, Ji-Jiang

supporting information, (2021/06/15)

A base/DMAP system for efficient oxidative cleavage of C(CO)–C(alkyl) bond to generate N-substituted benzamides has been developed in the presence of copper(I) chloride. The usage of inexpensive copper catalyst, broad substrate scope, mild conditions make

Singlet oxygen mediated dual C-C and C-N bond cleavage in visible light

Jain, Nidhi,Kumar, Sharvan,Ritu,Sharma, Charu

, p. 2921 - 2928 (2020/04/28)

A tandem cleavage of carbon-carbon and carbon-nitrogen bonds in imidazo[1,2-a]pyridines and imidazo[1,2-a]quinolines is reported in the presence of eosin Y and visible light. The ring opening occurs under ambient conditions through singlet oxygen insertio

Copper Catalyzed Oxidative C-C Bond Cleavage of 1,2-Diketones: A Divergent Approach to 1,8-Naphthalimides, Biphenyl-2,2′-dicarboxamides, and N-Heterocyclic Amides

Sakhare, Priyanka R.,Subramanian, Parthasarathi,Kaliappan, Krishna P.

, p. 2112 - 2125 (2019/02/14)

We report here a simple and efficient copper catalyzed oxidative C-C bond cleavage of stable aromatic cyclic-fused and acyclic 1,2-diketones to deliver amides and imides in high yields. This newly developed protocol provides an excellent tool to transform structurally different 1,2-diketones into different products under the same reaction conditions. The key synthetic features of this methodology are the formation of 1,8-naphthalimides and biphenyl-2,2′-dicarboxamide motifs in high yields. The fluorescent studies of 1,8-naphthalimide derivatives were also carried out in order to show the potential application of these scaffolds.
