Inorganic agents, with

The surface modification of an inorganic support with organophosphorus coupling agents (OPCA) is an extremely versatile route to hybrid materials. This route has been applied to a variety of supports, including metal oxides, metals, aluminosilicates, silica, metal hydroxides, and carbonates. 

Replacement of sulfuric acid in "mixed acid" aromatic nitrations by inorganic solids, with accumulation or elimination of produced water results in a fundamental different behaviour of the "HN03 - solid" couple. If water accumulates, nitric acid becomes a selective oxidative coupling agent, whereas when water is eliminated efficiently, nitric acid alone behaves as a strong nitrating agent, with increased paraselectivity as compared to the sulfo-nitric system.

The reactions of the aqueous electron (e aq) with specific organic and inorganic compounds have been studied extensively [4-6]. The e aq is a powerful reducing agent, with a reduction potential of —2.77 V. The reactions of the e aq are single-electron transfer, the general form of which is ...
