Abstract
Δ3-1,3,4-Oxadiazolin-2-ones are decomposed at moderate temperatures, either neat or in solution, by two parallel, first-order processes. One of these results in the formation of the appropriate diazomethane and carbon dioxide while the other leads to ketone, nitrogen, and carbon monoxide. Rates of these competing processes are reported along with some solvent effects and substituent effects on the product ratios.
