摘要

A cost-effective and convenient procedure for the synthesis of silica-supported 1-(2-sulfooxy)ethyl)1 H -pyridine-1-ium-chloride SiO~(2)/[SEP]Cl as a recoverable heterogeneous and Br?nsted acid catalyst is described, and was used for the one-pot synthesis of aryl-14 H -dibenzo[ a , j ]xanthenes under solvent- and metal-free conditions at 110?°C in short reaction time with a yield of up to 95%. The present method offers several advantages such as simplicity in operation, ease of preparation and recycling of Br?nsted acidic ionic liquid (BAIL), solvent-free reaction conditions, and no hazardous organic solvents are used in the entire procedure including workup and purification. Graphical abstract.
