چکیده

A simple extremely fast and efficient approach for the synthesis of substituted indazole in
good to excellent yield catalyzed by using silica sulfuric acid (SSA) in DMSO solvent at room
temperature. This is solid state reaction have been attracting the synthetic organic chemist as
they provided enhance reaction rates, less environmental pollution, greater selectivity, cleaner
products and manipulative simplicity. Various indazoles are obtained in moderate to excellent
yield.
