4703-19-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4703-19-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,7,0 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 4703-19:
(6*4)+(5*7)+(4*0)+(3*3)+(2*1)+(1*9)=79
79 % 10 = 9
So 4703-19-9 is a valid CAS Registry Number.

-

Paragraph 0121-0125; 0135-0140, (2021/03/16)

The present invention relates to a process for the preparation of diaryl amine compounds. A compound represented by chemical formula 1, a compound represented by chemical formula 2, and a synthetic reagent in a solvent, the synthetic reagent being CsF, KF, 18 - crown -6, K. 2 CO3, [TBAT] The present invention relates to a process for the preparation of diaryl amine compounds comprising a material selected from the group consisting of a (tetrabutylammonium difluorotriphenylsilicate), TBAF (tetrabutylammonium fluoride) and combinations thereof. Chemical Formula 1. Chemical Formula 2. The diaryl amine compound can be synthesized under the absence of a transition metal to be used to synthesize diaryl amine compounds having various substituents.

Transition-Metal-Free and Visible-Light-Mediated Desulfonylation and Dehalogenation Reactions: Hantzsch Ester Anion as Electron and Hydrogen Atom Donor

Heredia, Micaela D.,Guerra, Walter D.,Barolo, Silvia M.,Fornasier, Santiago J.,Rossi, Roberto A.,Budén, Mariá E.

, p. 13481 - 13494 (2020/12/15)

Novel approaches for N- and O-desulfonylation under room temperature (rt) and transition-metal-free conditions have been developed. The first methodology involves the transformation of a variety of N-sulfonyl heterocycles and phenyl benzenesulfonates to the corresponding desulfonylated products in good to excellent yields using only KOtBu in dimethyl sulfoxide (DMSO) at rt. Alternately, a visible light method has been used for deprotection of N-methyl-N-arylsulfonamides with Hantzsch ester (HE) anion serving as the visible-light-absorbing reagent and electron and hydrogen atom donor to promote the desulfonylation reaction. The HE anion can be easily prepared in situ by reaction of the corresponding HE with KOtBu in DMSO at rt. Both protocols were further explored in terms of synthetic scope as well as mechanistic aspects to rationalize key features of desulfonylation processes. Furthermore, the HE anion induces reductive dehalogenation reaction of aryl halides under visible light irradiation.

Transition-Metal-Free Diarylation of Isocyanates with Arynes

Jang, Woo Cheol,Hwang, Dong Wook,Seo, Jeong Hoon,Ko, Haye Min

supporting information, (2019/08/30)

A facile method for the transition-metal-free diarylation of isocyanates with arynes in the presence of cesium fluoride has been developed, which affords functionalized diaryl amines in moderate to excellent yields. This reaction has good functional group tolerance and provides excellent regioselectivity by utilizing a methoxy-substituted aryne precursor.
