一般描述

X-ray irradiated single crystals of 2,2,5-trimethyl-1,3-dioxane-4,6-dione have been investigated by electron spin resonance (ESR), electron nuclear double resonance (ENDOR) and electron-electron double resonance (ELDOR) spectra.

应用

2,2,5-Trimethyl-1,3-dioxane-4,6-dione was used for trapping the adduct formed during the reaction between alkyl isocyanides and dialkyl acetylenedicarboxylates.
