An Efficient, Simple, and Scaleable Domino Reaction to Diverse N-(1-Oxo-1H-inden-2-yl)benzamides Catalyzed by HPW@nano-SiO2 under Microwave Irradiation
A facile, efficient, and large-scale strategy for the synthesis of N-(1-oxo-1H-inden-2-yl)benzamide derivatives via domino reaction between aryl aldehydes, hippuric acid, and acetic anhydride catalyzed by HPW@nano-SiO 2 was accomplished undermicrowaveirradiation. The reaction conditions are very simple and offer easy isolation of the product. Moreover, the catalyst can be reused up to five times

A mild method for Friedel-Craftsacylation with aromatic and aliphatic carboxylic acids using cyanuric chloride, pyridine, and AlCl(3) was developed. Both inter- and intramolecular acylations were achieved at room temperature in high yield and in very short reaction times.
