Abstract
Dipole moment studies have revealed that furan-2-carboxylic acid esters exist in nonpolar solvents predominantly in O,O-cis-conformations. The dipole moment value of a 2-furoate ester depends on the electronic and steric effects of the substituents in the alcohol portion of the ester. The complex nature of the v C=O band region in the IR spectra of 2-furoates is due primarily to the appearance of resonance absorption bands.
