ZrCl4@Arabic Gum: An effective and environmentally friendly catalyst for the preparation of 14-aryl-14H-dibenzo[a,j]xanthene derivatives at ambient temperature without solvent %K 14-Aryl-14H-dibenzo[a %K j]xanthene derivatives Solvent-free condition ZrCl4@Arabic Gum Heterogeneous catalyst Green chemistry %R 10.22034/ajgc.2021.304712.1314 %X In this research, zirconium fixed on the Arabic Gum (ZrCl4@Arabi Gum) was used as a heterogeneous and recyclable Lewis acid catalyst for the one-pot synthesis of 14-aryl-14H-dibenzo[a,j]xanthene derivatives from the reaction of 2-naphthol, and various aldehydes under solvent-free conditions and at 70 ᵒC. The present method has many advantages such as catalyst reusability, high yields, non-toxic, easy of operation, short reaction time, environmentally friendly and high efficiency. %U https://www.ajgreenchem.com/article_141463_65b0cde9774074669cdea4bb16b59b15.pdf
