Benzotrichloride → 2-Phenylbenzothiazole
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Benzotrichloride | HCID 7367 | — |
| Reactant | Benzenethiol, 2-amino-, hydrochloride (1:1) | HCID 76794 | — |
| Product | 2-Phenylbenzothiazole | HCID 13439 | 33.1% |
Reaction Steps
As in Example 1b, 16.2 g (0.1 mol) of 2-aminothiophenol hydrochloride is reacted at 180° C bath temperature with 19.5 g (0.1 mol) of benzotrichloride (B). By extracting the reaction products with benzene and chromatographing the benzene extract on an Al2O3 column, 7.0 grams of Compound II were obtained, M.P. 105°-110° C (33% of the theory). A small specimen was recrystallized from ethanol: M.P. 113°-114° C.
