Synthesis and structural peculiarities of disodium 1,6-dioxoalka-2,4-diene-3,4-diolates

Abstract

Three-component condensation of dialkyl oxalates with alkyl acetates and alkyl methyl ketones in the presence of bases afforded 1-alkoxy(or 1,6-dialkoxy)-1,6-dioxoalka-2,4-diene-3,4-diolates. The product structure was discussed on the basis of their IR, 1 H NMR, and mass spectra.
