4,4'-Difluorobenzil Chemical Properties, Uses, Production

Chemical Properties

pale yellow powder

Uses

4,4′-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
