A variety of deactivated arenes were nitrated to their corresponding nitro derivatives in excellent yields under high-speed ball milling condition using Fe(NO3)3·9H2O/P2O5 as nitrating reagent. A radical involved mechanism was proposed for this facial, eco-friendly, safe, and effective nitration reaction.

A useful and efficient approach for the synthesis of nitroarenes from several aromatic amines (including heterocycles) using peroxide and base has been developed. This oxidative reaction is very easy to handle and afforded the products in good yields. Formation of benzamides from benzylamine was also successfully carried out with this metal-free catalytic system in good to excellent yields.

Highly effective embodiment of Sandmeyer reaction has been revealed for Cu-based catalysts incorporating ionic liquid on Silochrom support. The most active catalyst (TOF = = 4000–8000 h–1) contains comparable amounts of cuprous and cupric chloride anions. The reported method allows one to carry out the reaction for anilines in the one-pot mode.

The para-selective direct bromination and chlorination of nitrosoarenes with copper(II) bromide and chloride is reported. Under mild reaction conditions, a range of halogenated arylnitroso compounds are obtained in moderate to good yields with high regioselectivity. Additionally, the versatility of the method is demonstrated by the development of a one-pot procedure to obtain the corresponding para-halogenated aniline- and nitrobenzene derivatives.

, p. 167 - 171 (2007/10/03)
Alkylation of nitroarenes with Grignard reagents via oxidative nucleophilic substitution of hydrogen (ONSH) can be efficiently executed with potasium permanganate in liquid ammonia as an oxidative system for the σH adducts. The addition of RMgX to ArNO2 of stoichiometry 1:1 is accompanied with a redox process apparently of stoichiometry 2:1. Because of that, real stoichiometry of the reaction between nitroarenes and Grignard reagents is ca. 1:1.5.

Contacting of appropriately substituted nitrosobenzene with diphenylcyclopropenone under reflux conditions yields novel 2-aryl-3,4-diphenylisoxazolin-5-ones, which are useful as pharmacological agents in view of their serum triglyceride and cholesterol lowering properties.
