Allgemeine Beschreibung
4,4′-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.
Anwendung
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

Reaction of Fe(2)(SH)(2)(CO)(6) and HCHO, which gives Fe(2)[(SCH(2))(2)NH](CO)(6) in the presence of NH(3), affords the possible intermediate Fe(2)(SCH(2)OH)(2)(CO)(6), which has been characterized crystallographically as its axial-equatorial isomer. Fe(2)(SCH(2)OH)(2)(CO)(6) was shown to react with ammonia and amines to give Fe(2)[(SCH(2))(2)NR](CO)(6) (R
