Silver chloride as an efficient heterogeneous catalyst for the synthesis of different xanthenedione derivatives

Xanthenediones are an important class of organic compounds that have been used as dyes, fluorescent material for visualization of biomolecules and in laser technologies due to their useful spectroscopic properties 1. In the recent past, there is a renewed interest in the synthesis of this class of compounds as number of its applications increased, both in the field of medicinal chemistry and material science 2. We have demonstrated the method to study an efficiency of silver chloride catalyst to synthesize xanthenedione derivatives from the reaction of dimedone and different aromatic aldehydes at 80 °C in solvent free conditions (Figure 1).
