摘要

Dinitrophenols can be obtained via direct nitration of phenols with trichloroisocyanuric acid, NaNO 2 and wet SiO 2 at room temperature under solvent-free conditions with moderate to high yields. ... Recently, we have reported the applications of trichloroisocyanuric acid/NaNO 2 /wet SiO 2 system for the selective mononitration of phenols under mild and heterogeneous conditions. [3] Our goal, in undertaking this line of work, was three-fold: a) to overcome ...
