Prussian Blue as an Eco-Friendly Catalyst for Selective Nitration of Organic Compounds Under Conventional and Nonconventional Conditions

Abstract

Prussian blue (PB) has been developed as a new, mild, and eco-friendly catalyst for the nitration of aromatic compounds. Reactions underwent electrophilic substitution smoothly in presence of few drops of nitric acid. Reaction times of conventional methods were enormously reduced from 6–8 h to about 1–1.5 h in ultrasonically assisted and to about 3 min in microwave-assisted reactions.
