General description

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.

Application

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.

The adduct produced in the reaction between alkyl isocyanides and dialkyl acetylenedicarboxylates was trapped by 2,2,5-trimethyl-1,3-dioxane-4,6-dione (methyl Meldrum's acid), to afford highly functionalized ketenimines in good yields.
