Description

MilliporeSigma Sigma Organics products encompass a wide range of quality reagents, solvents, catalysts, and building blocks for organic synthesis. From benchtop discovery to process development and scale-up, Sigma Organics solutions are built to meet the needs of synthetic chemists.

  • Formaldehyde diethyl acetal (fdea, diethoxymethane, dem) is a diethyl acetal
  • It has been synthesized from ethanol and aqueous formaldehyde
  • It is a low boiling solvent useful for sodium hydride reactions, organolithium chemistry, copper-catalyzed conjugate additions and phase-transfer reactions
  • It is a potential alternate for tetrahydrofuran, dichloromethane, glyme and methylal
  • Dem is an ethoxymethylating agent, a formaldehyde equivalent and a carbonylation substrate
  • Its condensation with 2-propylresorcinol to form resorcin[n]arenes (n=4-7) has been investigated
  • The IR and raman spectra and conformations of dem have been studied
  • NMR spectroscopy has been used to study the aggregation behavior of organolithium compounds in diethoxymethane
  • Unimolecular metastable decomposition of dem upon electron impact has been studied
  • Solubility of non-polar gases in dem has been evaluated.formaldehyde diethyl acetal may be used as a solvent in the esterification of carboxylic acids and in the o-alkylation of a variety of phenols
