| | 2,4-Difluoronitrobenzene Usage And Synthesis |
| Synthesis | KF with n-Hexadecyltrimethylammonium bromide as the PTC has been shown
recently to work in dimethylformamide (DMF), important owing to the low cost16 of
DMF. | | Chemical Properties | yellow liquid | | Uses | 2,4-Difluoronitrobenzene has been used in the synthesis of 2,4-difluoro-5-nitrobenzenesulfonic acid via sulfonation reaction, (±)-horsfiline and resin-bound-2-arylaminobenzimidazoles. | | Uses | 2,4-Difluoronitrobenzene has been used in the synthesis of:
- 2,4-difluoro-5-nitrobenzenesulfonic acid via sulfonation reaction
- (±)-horsfiline
- resin-bound 2-arylaminobenzimidazoles
| | Uses | 2,4-Difluoronitrobenzene has been used in the synthesis of:
2,4-difluoro-5-nitrobenzenesulfonic acid via sulfonation reaction;
(±)-horsfiline;
resin-bound 2-arylaminobenzimidazoles.
2,4-Difluoronitrobenzene is a reactant in the preparation of 4-thiazolidinone derivatives as antimicrobial agents. | | General Description | Nucleophilic aromatic substitution of 2,4-difluoronitrobenzene with morpholine has been investigated using flow reactor with simulated moving bed (SMB) chromatography module. | | References | [1] Catalysis Today, 2012, vol. 198, # 1, p. 300 - 304
