Abstract

Acridine reacts with red phosphorus in the KOH/DMSO(H₂O) system on heating (100°C, 3 h) to give 9,10-dihydroacridine regioselectively in quantitative yield. Under similar conditions, 9-chloroacridine reacts with P_red/KOH/DMSO(H₂O) system to afford 9,10-dihydroacridine and acridone in 51 and 40% yield, respectively.
