Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Phosphorus pentachloride | HCID 24819 | — |
| Reactant | 2,3-Dioxoindoline-5-carbonitrile | HCID 12351495 | — |
| Product | 5-Cyanoisatin chloride | HCID 20351112 | — |
Reaction Steps
By reacting 5-cyanoisatin with phosphorous pentachloride, there is obtained 5-cyanoisatin chloride which, on reaction with 3(2H)-thianaphthenone, yields 5'-cyano-2'-indole-2-thianaphthenone indigo, which also is useful as a dyestuff.
