Fischer Indole Synthesis using γ-Fe2O3@SiO2-PW as an Green and recyclable catalyst

A simple, efficient and an environmental friendly method have been developed for the synthesis of substituted indole from aryl hydrazines and aldehydes/ ketones with γ- Fe2O3@SiO2-PW as a heterogeneous catalyst. The catalyst is recyclable and gives high yield in short reaction tim.
