137742-63-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 137742-63-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,7,4 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 137742-63:
(8*1)+(7*3)+(6*7)+(5*7)+(4*4)+(3*2)+(2*6)+(1*3)=143
143 % 10 = 3
So 137742-63-3 is a valid CAS Registry Number.

Microwave assisted fluorofunctionalization of phenyl substituted alkenes using selectfluor

Kumar, Anil,Singh, Tej Vir,Venugopalan, Paloth

, p. 72 - 77 (2013/06/05)

A rapid fluorofunctionalization of alkenes and diene using selectfluor has been uncovered. The olefins such as 1-phenyl ethene; 1,1-diphenylethene; (E)-1,2-diphenylethene; (E)-1,2-dinaphthylethene; 1,1,2-triphenylethene; 1,1,2,2-tetraphenylethene and 1,1,

N-Fluorobisimides: Reactions with Some Olefins via α-Fluoro Carbocationic Intermediates

DesMarteau, Darryl D.,Xu, Ze-Qi,Witz, Michael

, p. 629 - 635 (2007/10/02)

N-Fluorobisimides are a new class of electrophilic fluorinating agents.Reaction of (CF3SO2)2NF (1) with olefins gave various products, depending on the reaction conditions and the structure of the substrate.In solvents of higher nucleophilicity such as H2O, acetic acid, aqueous HCl, and (HF)nPy, α-fluorohydrins and their acetates, α,β-chlorofluoro- and α,β-difluoroalkanes were obtained.In acetic acid, trans-stilbene and tetraphenylethylene produced the rearranged, nonfluorinated aldehyde and ketone.Evidence is presented for the reactions proceeding via a one-electron transfer mechanism involving α-fluorocarbocationic intermediates.
