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 reduced thermal stability of ethyl halodiazoacetates compared to ethyl diazoacetate and for the relative decomposition rates between the chloro, bromo
已经获得了卤代偶氮乙酸乙酯的热分解速率(卤代= Cl,Br,I),并且本文报道了它们的半衰期。DFT计算支持了实验结果,并且我们提供了与重氮乙酸乙酯相比卤代重氮乙酸乙酯的热稳定性降低以及氯代,溴代和碘代类似物之间的相对分解速率的可能解释。我们还简要地研究了苯乙烯的热非催化环丙烷化,并将结果与类似的Rh(II)催化反应进行了比较。
