312-66-3 Usage
General Description
2,2,3,3,4,4,4-Heptafluorobutyl p-toluenesulfonate is a chemical compound, specifically an organofluorine compound, which is often used as a reagent in preparative organic chemistry due to its characteristic perfluoroalkylating properties. As its fluorine atoms are extremely electron withdrawing, the compound presents high thermal and chemical stability, along with significant lipophilicity. Notably, these characteristics can be transferred to other molecules when used as a reagent in chemical reactions, making it valuable for the creation of many unique synthetic compounds. Its potential health effects and environmental impacts have not been extensively studied.
Check Digit Verification of cas no
The CAS Registry Mumber 312-66-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 3,1 and 2 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 312-66:
(5*3)+(4*1)+(3*2)+(2*6)+(1*6)=43
43 % 10 = 3
So 312-66-3 is a valid CAS Registry Number.

Synthesis of alkyl perfluoroalkanedithiocarboxylates and some aspects of their reactivity in cycloaddition reactions
Portella, Charles,Shermolovich, Yuri G.,Tschenn, Olivier
, p. 697 - 702 (2007/10/03)
A new method for the synthesis of the title compounds is proposed.The starting fluorinated compounds are commercially available trifluoroethanol and higher homologues, which were transformed in three steps into (2,2-dichloroperfluoroalkyl) alkylsulfides.The last step consisted in a substitution of chlorine by sulfur by treatment with zinc sulfide.The source of zinc sulfide is crucial and the possible role of catalytic impurities was investigated.These dithioesters are excellent dienophiles.Some cycloaddition reactions with 2,3-dimethylbuta-1,3-diene and 1-(trimethylsilyloxy)buta-1,3-diene are reported. - Keywords: perfluorinated dithioester; polyfluorinated sulfide; cycloaddition; tetrahydrothiopyran
