On the cause of low thermal stability of ethyl halodiazoacetates
Beilstein Journal of Organic Chemistry, 2016 Rates for the thermal decomposition of ethyl halodiazoacetates (halo = Cl, Br, I) have been obtained, and reported herein are their half-lives. The experimental results are supported by DFT calculations, and we provide a possible explanation for the ...
