652-23-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 652-23-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,5 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 652-23:
(5*6)+(4*5)+(3*2)+(2*2)+(1*3)=63
63 % 10 = 3
So 652-23-3 is a valid CAS Registry Number.

Palladium-catalyzed base-free Suzuki-Miyaura coupling reactions of fluorinated alkenes and arenes via a palladium fluoride key intermediate

Ohashi, Masato,Saijo, Hiroki,Shibata, Mitsutoshi,Ogoshi, Sensuke

supporting information, p. 443 - 447 (2013/02/26)

A new strategy for C-C bond formation with organoboronates through C-F activation of fluorinated alkenes and arenes was developed. In this Pd-catalyzed Suzuki-Miyaura-type cross-coupling reaction, neither a base for enhancing the reactivity of the organoboron reagents nor a Lewis acid for promoting C-F bond activation was required. A fluoropalladium intermediate played an essential role in this reaction. In addition, a Ni(NHC) catalyst was efficient for C-C coupling through C-F bond activation of fluoroarenes. Pd0/PR 3 complexes promote C-C bond formation with organoboronates through C-F bond activation of fluorinated alkenes. Mechanistic studies show that a PdII fluoride intermediate plays an essential role in this base-free cross-coupling reaction. Moreover, a Ni(NHC) catalyst is efficient for C-C coupling through C-F bond cleavage of fluoroarenes. Copyright

Thermolytic transformations of polyfluoroorganic compounds 30. Copyrolysis of α,α-dichlorooctafluoroethylbenzene with tetrafluoroethylene

Dvornikova, K. V.,Platonov, V. E.,Yakobson, G. G.

, p. 1690 - 1693 (2007/10/02)

The reaction of α,α-dichlorooctafluorobenzene with tetrafluoroethylene as a source if difluorocarbene has been studied.The copyrolysis of these compounds gave not only the expected products, decafluoro-α-methylstyrene and α-chloroheptafluorostyrene, but also noticeable amounts of perfluoro-1-methylindan and perfluoro-7-methylbicyclonona-1,4,6-triene along with perfluoro-3-methylindene and octafluorostyrene.It has been suggested that indan and the triene are formed with the participation of the C6F5CClCF3 radical through sigmatropic shifts of fluorine atoms in the intermediate bicyclic compounds.The reaction of α,α-dichlorodecafluoropropylbenzene with tetrafluoroethylene afforded α-chloroheptafluorostyrene as the main product. - Key words: copyrolysis; decafluoro-α-methylstyrene, perfluoro-7-methylbicyclonona-1,4,6-triene; perfluoro-1-methylindan; polyfluoroalkylbenzyl radicals; sigmatropic shifts of fluorine atoms.
