28394-83-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 28394-83-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,8,3,9 and 4 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 28394-83:
(7*2)+(6*8)+(5*3)+(4*9)+(3*4)+(2*8)+(1*3)=144
144 % 10 = 4
So 28394-83-4 is a valid CAS Registry Number.

A facile synthetic route to benzimidazolium salts bearing bulky aromatic N-substituents

Grieco, Gabriele,Blacque, Olivier,Berke, Heinz

, p. 1656 - 1666 (2015)

An atom-economic synthetic route to benzimidazolium salts is presented. The annulated polycyclic systems: 1,3-bis(2,4,6- Trimethylphenyl)-1H-benzo[d]imidazol-3-ium chloride (1-Cl), 1,3-bis(2,6-diisopropylphenyl)-1H-benzo[d]imidazol-3-ium chloride (2-Cl),

Benzannulated N-heterocyclic germylenes and stannylenes with sterically demanding N,N′-substituents

Krupski, Sergei,Poettgen, Rainer,Schellenberg, Inga,Hahn, F. Ekkehardt

, p. 173 - 181 (2014)

Four N,N′-disubstituted 1,2-diaminobenzes (1a: R = t-Bu, 1b: R = adamantyl, 1c: R = Ph, 1d: R = Dipp) have been prepared and reacted with E[N(SiMe3)2]2 (E = Ge, Sn) to give the benzannulated N-heterocyclic germylenes 2a-d

A Ring Expansion Route to Benzofused N-Heterocycles Through Aryne Insertion into 1,3-Diaza-heterocycles

Yang, Yun,Xu, Yue,Jones, Christopher R.

supporting information, p. 5196 - 5200 (2019/06/25)

Arynes have been found to undergo formal σ-bond insertion into a C(sp3)–N bond for the first time. This transformation is utilized in the ring expansion of 1,3-diaza-heterocycles to afford benzofused medium-ring N-heterocycles in a single step. This represents a novel route to biologically relevant 2,3,4,5-tetrahydro-1H-benzo[e][1,4]diazepine?s, prepared directly from easily accessible imidazolidines. An example of the ring expansion of a 1,3-diazetidine is also reported, which affords the corresponding 1,2,3,4-tetrahydroquinazoline.

Iodine-catalyzed synthesis of N, N ′-diaryl-o-phenylenediamines from cyclohexanones and anilines using DMSO and O2 as oxidants

Xiong, Mingteng,Gao, Zhan,Liang, Xiao,Cai, Pengfei,Zhu, Heping,Pan, Yuanjiang

, p. 9679 - 9682 (2018/09/10)

A novel I2-catalyzed cross-dehydrogenative aromatization of cyclohexanones and anilines to synthesize N,N′-diaryl-o-phenylenediamines has been unprecedentedly developed with dimethyl sulfoxide and oxygen employed as mild terminal oxidants. To prove the rationality of the two separate dehydration steps of the proposed mechanism, a resulting I2-catalyzed cross-dehydrogenative aromatization of cyclohexenones and anilines to synthesize diarylamines has also been reported.
