Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Hydrazine | HCID 9321 | — |
| Reactant | 1,2-Difluoro-4-nitrobenzene | HCID 123053 | — |
| Solvent | Isopropanol | HCID 3776 | — |
| Product | 2-fluoro-4-nitrophenylhydrazine | HCID 3809170 | 90.6% |
Reaction Steps
A solution of 3.2 g (0.10 mole) of hydrazine in 20 mL of isopropanol was added with stirring to a solution of 15.9 g (0.10 mole) of 3,4-difluoronitrobenzene in 60 mL of isopropanol. Upon completion of addition the reaction mixture was heated under reflux for 30 minutes. The reaction mixture was concentrated under reduced pressure to yield 15.5 g of 2-fluoro-4-nitrophenylhydrazine; m.p. 119°-121° C.
