A Clean, Mild, and Efficient Preparation of Aryl 14H-benzo[a, j] xanthene leuco-dye Derivatives via Nanocatalytic MCM-41-SO3H under Ultrasonic Irradiation in Aqueous Media

摘要

Aim and Objective: The present study has developed an efficient and eco-friendly protocol for the synthesis of aryl-14-H-dibenzo[a, j] xanthenes through a one-pot condensation reaction of 2-naphthol and arylaldehydes in aqueous media using the nanocatalytic MCM-41-SO3H under ultrasonic illumination.
