General Description
2-Dibenzothiophenamine is a chemical compound with the molecular formula C12H9NS. It is commonly used as a building block in organic synthesis, particularly in the production of pharmaceuticals and agrochemicals. 2-Dibenzothiophenamine is a derivative of benzothiophene, containing two benzene rings attached to a thiophene ring. 2-Dibenzothiophenamine is known for its strong nucleophilic character and is often used as a reagent in various chemical reactions, such as Suzuki coupling and palladium-catalyzed cross-coupling reactions. It also has potential applications in the development of new materials and polymers due to its unique molecular structure.
Check Digit Verification of cas no
The CAS Registry Mumber 7428-91-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,2 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 7428-91:
(6*7)+(5*4)+(4*2)+(3*8)+(2*9)+(1*1)=113
113 % 10 = 3
So 7428-91-3 is a valid CAS Registry Number.

Desulfurization of Benzo- and Dibenzothiophenes with Nickel Boride
Back, Thomas G.,Yang, Kexin,Krouse, H. Roy
, p. 1986 - 1990 (2007/10/02)
Nickel boride, prepared from the reduction of nickel chloride hexahydrate with sodium borohydride in methanol-tetrahydrofuran, reduces benzothiophenes to alkylbenzenes and dibenzothiophenes to biphenyls.The reaction is rapid at or below room temperature and does not require protection from the atmosphere.Best results are obtained when the nickel boride is generated in situ in the presence of the sulfur compound.Hydroxyl, carboxyl, ester, and amino groups are unaffected while chloro, bromo, and nitro substituents are also reduced under these conditions.A short-livedintermediate, possibly a nickel hydride species, appears to be required in the desulfurization.Complexation of the substrate to the nickel boride surface, followed by stepwise reduction of the two C-S bonds, occurs.The faster disappearance of dibenzothiophene containing the lighter 32S isotope compared to that with 34S (k(32S)/k(34S) = 1.005 to 1.006) suggests that C-S bond cleavage is the rate-determining step.
