Uses
3-Bromo-4-fluorotoluene was employed as starting reagent in the synthesis of [4-fluoro-3-(trimethylsilyl)benzyl]guanidine. It was also employed as benzyne precursor in the synthesis of 6-methyl-1,2,3,4-tetrahydro-2,3-(benzylidenedioxy)-1,4-ethenonapthalene.
Check Digit Verification of cas no
The CAS Registry Mumber 452-62-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,5 and 2 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 452-62:
(5*4)+(4*5)+(3*2)+(2*6)+(1*2)=60
60 % 10 = 0
So 452-62-0 is a valid CAS Registry Number.

Process for the preparation of fluoroaromatic compounds substituted in the o-position
-
, (2008/06/13)
Ortho-substituted fluoroaromatic compounds are prepared by reaction of corresponding anilines, which are substituted in the o-position, with alkyl nitrites in the presence of alcohols and/or ethers and in the presence of boron trifluoride or boric acid esters and hydrogen fluoride, and by isolation and decomposition of the diazonium tetrafluoborate produced.
