… In this article, we report a new, simple, cheap, and convenient protocol for the
mononitration of phenols using SiO 2 –OSO 3 H and Al(NO 3 ) 3 ·9H 2 O in the presence of
wet SiO 2 (50% w/w) under mild and heterogeneous conditions. … A combination of
aluminum nitrate nine hydrate and silica sulfuric acid can act as a solid nitrating agent,
which can be readily weighed, handled, and used in the presence of moist SiO 2 . Water
molecules or wet SiO 2 are necessary for the … In summary, herein, we report an efficient …
