Carbon and oxygen isotope effects in the decarbonylation of benzoylformic acid in concentrated sulphuric acid
Abstract
Kinetic isotope effects for carbon and oxygen for the decarbonylation of benzoylformic acid in concentrated sulphuric acid have been measured, which together with measurements on isotopic exchange of oxygen with the solvent, support a mechanism in which C–O bond rupture occurs in the rate-determining step.
