Calculate Digit Verification of CAS Registry Number 1264737-47:
(9*1)+(8*2)+(7*6)+(6*4)+(5*7)+(4*3)+(3*7)+(2*4)+(1*7)=174
174 % 10 = 4
So 1264737-47-4 is a valid CAS Registry Number.

Synthesis of CF3-substituted sulfoximines from sulfonimidoyl fluorides

Kowalczyk, Rafal,Edmunds, Andrew J. F.,Hall, Roger G.,Bolm, Carsten

, p. 768 - 771 (2011/04/24)

N-Protected trifluoromethyl-substituted sulfoximines have been prepared by treatment of sulfonimidoyl fluorides with a combination of the Ruppert-Prakash reagent (TMSCF3) and tetrabutyl ammonium fluoride (TBAF). The starting materials were accessed following two synthetic routes, and for each reaction sequence the substrate scope was evaluated. Accordingly, a wide variety of aryl-substituted products were obtained in moderate to good yield.
