4,4'-DIFLUOROBENZIL Usage And Synthesis
Chemical Propertiespale yellow powder
Uses4,4′-Difluorobenzil is suitable for use in the preparation of 2,3-bis(4-fluorophenyl)thieno[3,4-b]pyrazine. It may be used in the synthesis of following:
  • poly(ether-α-diketone)s, via nucleophilic substitution reaction with bisphenol A
  • 4,4′-difluoro-2,3-diphenylpyrazine (DPPF) and 4,4′-difluoro-5-methyl 2,3-diphenylpyrazine (MDPPF), via direct condensation with ethylenediamine and 1,2-diaminopropane, respectively
  • 2,3-bis(4-fluorophenyl)quinoxaline, via direct condensation with 1,2-phenylenediamine
Synthesis Reference(s)Tetrahedron Letters, 35, p. 2959, 1994 DOI: 10.1016/S0040-4039(00)76671-8
General Description4,4′-Difluorobenzil is a benzil derivative. Its reaction with benzylurea and phenethylurea has been investigated. It is reported to undergo condensation with Fe2(SH)2(CO)6 to afford the adduct Fe2[S2C2(OH)2(C6H4-4-F)2](CO)6.
