Table 1. Impact Sensitivity (IS), Thermal Stability, and Exotherm Data Previously Reported for Diazo Compounds^{10,15,25−43}.

^aMeasured by DSC unless otherwise noted.

^bHeating rate not given.

^cDSC of 40% weight ethyl diazoacetate (EDA) in toluene. ΔH_D reported was −602 J g^–1, which was extrapolated to 100% weight EDA assuming a linear relationship.

^dMeasured by ARC on neat EDA, a much more sensitive instrument and slower heating rate and so T_onset is lower and ΔH_D is higher than a typical DSC experiment.

^eEstimated from DSC plot given in Supporting Information.

^fDSC peak maxima temperatures.

^gDistinction between T_init and T_onset was unclear; so, we have assumed T_init as defined in this work.

^hMeasured by thermogravimetric analysis (TGA).

ⁱInterestingly, this compound is reported to cyclize into a pyrazole rather than evolving N₂ gas.

^jDistinct second decomposition is observed.
