Mutagenic N-acetoxy-N-butoxybenzamides undergo acid catalysed solvolysis in acetonitrile/water. Kinetic data and a Hammett σ+ correlation (ϱ=−1.4) indicate nitrenium ionformation in the rate determining step. Levels of mutagenicity mirror the rates of solvolysis suggesting nitrenium ion involvement.
