Abstract

Abstract The intramolecular hydrogen bonding in ethyl ω-alkylamino-acetates and -propionates in dilute carbon tetrachloride solutions has been investigated through the measurement of the NH and CO stretching absorption spectra. In the α-esters, the spectral data give no evidence regarding the hydrogen-bond formation. In the β-esters, though, the hydrogen bonding occurs, probably predominantly between the NH and the CO group.
