1638291-19-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1638291-19-6 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,3,8,2,9 and 1 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1638291-19:
(9*1)+(8*6)+(7*3)+(6*8)+(5*2)+(4*9)+(3*1)+(2*1)+(1*9)=186
186 % 10 = 6
So 1638291-19-6 is a valid CAS Registry Number.

Room-temperature ortho-alkoxylation and -halogenation of N-tosylbenzamides by using palladium(II)-catalyzed C-H activation

Peron, Florent,Fossey, Christine,Sopkova-Deoliveirasantos, Jana,Cailly, Thomas,Fabis, Frederic

, p. 7507 - 7513 (2014/06/23)

The N-tosylcarboxamide group can direct the room-temperature palladium-catalyzed C-H alkoxylation and halogenation of substituted arenes in a simple and mild procedure. The room-temperature stoichiometric cyclopalladation of N-tosylbenzamide was first studied, and the ability of the palladacycle to react with oxidants to form C-X and C-O bonds under mild conditions was demonstrated. The reaction conditions were then adapted to promote room-temperature ortho-alkoxylations and ortho-halogenations of N-tosylbenzamides using palladium as catalyst. The scope and limitation of both alkoxylations and halogenations was studied and the subsequent functional transformation of the N-tosylcarboxamide group through nucleophilic additions was evaluated. This methodology offers a simple and mild route to diversely functionalized arenes.
