Hammett Correlation

The thermal decomposition of 3-chloro-3-aryldiazirines in various solvents has been investigated over the temperature range 60–100 °C. The intermediate carbenes have been isolated as norcaranes by the use of cyclohexene. Substituent effects on rates of reaction are small and a Hammett correlation was unsuccessful with either σ or σ+ constants. Possible mechanisms for the decompositions are discussed.
