54682-58-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 54682-58-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,6,8 and 2 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 54682-58:
(7*5)+(6*4)+(5*6)+(4*8)+(3*2)+(2*5)+(1*8)=145
145 % 10 = 5
So 54682-58-5 is a valid CAS Registry Number.

Palladium catalyzed aryl C-H amination with O2via in situ formation of peroxide-based oxidant(s) from dioxane

Weinstein, Adam B.,Stahl, Shannon S.

, p. 4301 - 4307 (2014)

(DAF)Pd(OAc)2 (DAF = 4,5-diazafluorenone) catalyzes aerobic intramolecular aryl C-H amination with N-benzenesulfonyl-2-aminobiphenyl in dioxane to afford the corresponding carbazole product. Mechanistic studies show that the reaction involves i

Paragraph 0058-0062; 0108-0118, (2021/11/27)

The invention relates to a method for electrochemical synthesis of a carbazole compound. The method comprises the following steps: taking an N-substituted acylamino biphenyl derivative as a substrate,adding the substrate and an electrolyte into an organic

Silver-copper co-catalyzed cascade intramolecular cyclization/desulfinamide/dehydrogenation: One-pot synthesis of substituted carbazoles

Huang, Yuanqiong,Guo, Zhonglin,Song, Hongjian,Liu, Yuxiu,Wang, Qingmin

, p. 7143 - 7146 (2018/07/05)

Herein, a silver and copper co-catalyzed cascade intramolecular cyclization/desulfinamide/dehydrogenation reaction for the synthesis of substituted carbazoles is reported. This reaction, which involved formation of new C-C and C-N bonds as well as C-N bond cleavage, afforded diverse carbazoles in high yields and showed good functional group tolerance.
