Nano-SnCl4·SiO2 - A versatile and efficient catalyst for synthesis of 14-aryl- or 14-alkyl- 14H-dibenzo[a·j]xanthenes

2-Naphthol and various aldehydes were used for the synthesis of 14-aryl- or 14-alkyl-14H-di-benzo[a,j]xanthene in the presence of nano-SnCl 4·SiO2 under solvent-free condition. Nano-SnCl 4·SiO2 is an efficient,

Highly ordered acid functionalized SBA-15: A novel organocatalyst for the preparation of xanthenes

Post-synthesis modification of SBA-15 has been carried out to design highly ordered acid functionalized hybrid mesoporous organosilica, AFS-1. This material has been used as an efficient heterogeneous organocatalyst for the syntheses of xanthenes under mi

Synthesis of dibenzoxanthenes through condensation of β-naphthol with various aromatic and aliphatic aldehydes in ethanol as an ecofriendly solvent using RuIII as catalyst is reported.

Polystyrene-supported aluminum chloride: An efficient and recyclable green catalyst for one-pot synthesis of 14-aryl or alkyl-14h-dibenzo[a,j]xanthenes

A new, mild, and efficient method has been developed for the one-pot synthesis of 14-aryl or alkyl-14H-dibenzo[a, j]xanthenes by condensation of 2-naphthol and aryl or alkyl aldehydes in the presence of a catalytic amount of cross-linked polystyrene-suppo

Assembling of H5PW10V2O 40/MCM-48 and studying its superior catalytic performance in the synthesis of 14-aryl-14-H-dibenzo[a, j]xanthenes

A highly efficient, green, and reusable heterogeneous catalytic system is introduced for the preparation of aryl-14-H-dibenzo[a,j]xanthenes via one-pot condensation of β-naphthol with aryl-aldehydes by the mediation of a heterogeneous material composed of

Design and characterization of [(Et)3?N-H]FeCl4 as a nanomagnetic ionic liquid catalyst for the synthesis of xanthene derivatives under solvent-free conditions

The triethylamine-based nanomagnetic ionic liquid, [(Et)3?N-H]FeCl4, was synthesized, and its structural and chemical characteristics were detected. The thermogravimetric analysis indicated its high thermal stability with a decomposi

A rapid and quantitative synthesis of xanthene derivatives using sulfonated graphitic carbon nitride under ball‐milling

A truly green, solventless, and fast protocol for the quantitative preparation of biologically active xanthene derivatives with 10 mol% sulfonated graphitic carbon nitride (Sg─CN) as a heterogeneous acidic catalyst was developed. Excellent yields, low cost, solvent‐free conditions, high catalytic activity, reusability of the catalyst, simple workup, and heterogeneous carbon‐based catalyst make the present method particularly attractive from a green chemistry perspective.

Solvent-free synthesis of 14-aryl-14H-dibenzo[a-j]xanthenes using Fe3O4@Al2O3@SiO2@Fe2O3 as a green catalyst

We report, a novel, green, nano-sized particles as a sandwich nano-capsule multilayer catalyst (SNC@MC) [Fe3O4@Al2O3@SiO2@Fe2O3] for the efficacious one-pot synthesis of 14-aryl-
