Nitration reactions are extensively studied in organic synthesis despite their notorious
dangers, high reaction rates, and heterogeneous reaction systems. To date, most industrial …

This report describes an efficient nitrating system for the nitration of arenes at room
temperature by using an equivalent of nitric acid in HFIP (1, 1, 1, 3, 3, 3 …

Silica supported molybdenum oxide modified with phosphoric acid (P/Mo/SiO 2) is a very
active solid acid catalyst in ortho-xylene nitration. At room temperature and with a small …

A solvent-free, acid-free, and efficient strategy was developed for the selective preparation of
4-nitro-o-xylene (4-NOX) from the catalytic nitration of o-xylene with NO2 mediated O2 over …

Nitration of o-xylene with nitrogen dioxide imparts remarkable selectivity to 4-nitro-o-xylene.
The addition of Brønsted acids and Lewis acids can effectively improve the selectivity for 4 …

Nitration of aromatic compounds is one of the most important chemical reactions and widely
used in chemical industry. Classical nitration based on nitric acid and sulfuric acid is quite …

Diatomite-entrapped hydrosulfate catalysts with the enhanced acidity were prepared by
impregnation and 20 wt% KHSO 4/diatomite was selected as a heterogeneous catalyst for …
