Facile and Efficient Synthesis of 14‐Alkyl‐ or Aryl‐14‐H‐Dibenzo[a,j]xanthenes using Sulfonyl‐Functionalized Ionic Liquids

Abstract

Abstract An efficient, simple, and rapid synthesis of 14‐alkyl‐or aryl‐14‐H‐dibenzo[a,j]xanthenes is reported by one‐pot condensation of 2‐naphthol with alkyl or aryl aldehydes in the presence of sulfonyl‐functionalized acidic ionic liquids at 125°C.
