Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 2,3,6-Trichloroquinoxaline | HCID 18070 | — |
| Reactant | Hydrazine hydrate (1:1) | HCID 24654 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | 2,6-Dichloro-3-hydrazinylquinoxaline | HCID 1473346 | — |
Reaction Steps
A mixture consisting of 23 g. (0.10 mole) of 2,3,6-trichloroquinoxaline and 11 g. (0.22 mole) of hydrazine hydrate in 500 ml. of ethanol was stirred at room temperature (~20° C.) overnight (~16 hours). The precipitate which formed was separated by filtration and washed with ethanol to ultimately afford 22.2 g. (97%) of pure 2,6-dichloro-3-hydrazinoquinoxaline, m.p. <250° C.
