Aqueous Sulfuric Acid

The nitration of some tertiary phosphine oxides ArP(O)R2 in aqueous sulfuric acid has been investigated. All compounds studied react as conjugate acids. When the phosphinyl group is bonded directly to the benzene ring, high deactivation and meta-orientation is found, accompanied in most cases by some substitution at the ortho position. The substituent effects of the "quasiphosphonium" group P(OH)R2+are compared with those of structurally related systems and are discussed in terms of pπ–dπ, interactions of the oxygen and the phosphorus atom.

Aqueous Sulfuric Acid

Phenyl-aci-nitromethane reacts in aqueous sulfuric acid at room temperature to form phenylnitromethane and benzohydroxamic acid. The relative amounts of these two products depend on the concentration of the acid. Benzohydroxamic acid is formed by reaction of the intermediate, benzonitrile oxide, with water.Solvent effects, substituent effects, and isotope effects have been studied to determine mechanisms for these reactions of phenyl-aci-nitromethane.
