A comparative study of the kinetics of the N-nitrosation of sulfanilamide by cyclohexyl nitrite and by nitrous acid has been made, using an automated technique. The results indicate that a common nitrosating species is effective in analogous reactions involving cyclohexyl nitrite or nitrous acid. Th

The rate constants were determined for the nitrosation reactions of the following substrates: Methyl (MU), Ethyl (EU),Propyl (PU)Butyl (BU), and Allylurea (AU). The rate equation found at a constant pH was: [Urea]. The reactions were carried out in pre-v ϭ k[HNO ] 2 dominantly organic media(dioxane
## Abstract The kinetics of the nitrosation of 1,3‐dimethyl (DMU), 1,3‐diethyl (DEU), 1,3‐dipropylurea (DPU), 1,3‐dibuthyl (DBU), and 1,3‐diallylurea (DAU) were studied in a conventional UV/vis spectrophotometer in aqueous‐perchloric acid media. The kinetic study was carried out using the initial r
~SN CIDNP effects observed during nitration of phenolic compounds with nitric and nitrous acid are comparable showing that nitrous acid is not only a catalyst during nitration with nitric acid but also a reactive intermediate. The ~SN CIDNP effects are generated in radical pairs formed during encoun
