Uses
4-Dimethylaminosulfotoluidide is an intermediate in the synthesis of Tolylfluanide (T536730), a polyvalent sulfamide fungicide that is closely related to dichlofluanide.
Definition
ChEBI: A member of the class of sulfamides that is N,N-dimethylsulfuric diamide substituted by a 4-methylphenyl group at the amino nitrogen atom. It is a metabolite of the agrochemical tolylfluanid.
Check Digit Verification of cas no
The CAS Registry Mumber 66840-71-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,6,8,4 and 0 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 66840-71:
(7*6)+(6*6)+(5*8)+(4*4)+(3*0)+(2*7)+(1*1)=149
149 % 10 = 9
So 66840-71-9 is a valid CAS Registry Number.

Synthesis of CF3CH2-Containing Indolines by Transition-Metal-Free Aryltrifluoromethylation of Unactivated Alkenes

With an unactivated double bond as the radical acceptor, allyl amines underwent a metal-free trifluoromethylation/cyclization cascade with CF3SO2Na (Langlois' reagent), affording CF3CH2-containing indolines and tetrahydroisoquinolines, whose practical syntheses are significant challenges. This protocol features mild conditions, low cost, and a broad substrate scope.
