Popis: | 4,6,7-Trichloro-2-hetarylamino-5-hydroxy-2,3-dihydrobenzo[b]furans have been prepared from 4,6,7-trichloro-2,5-dihydroxy-2,3-dihydrobenzo[b]furan and hetarylamines. Reductive opening of the dihydrobenzofuran ring in these compounds gave 3,5,6-trichloro-2-(β-hetarylaminoethyl)hydroquinones. The latter could be oxidised to the target 3,5,6-trichloro-2-(β-hetarylaminoethyl)-1,4-benzoquinones which are novel 1,4-benzoquinone derivatives with intramolecular charge transfer. |
