Electronic spectra of α,β-unsaturated carbonyl compounds—III : β-alkylamino and β-dialkylamino acrylamides

Several β-alkylamino, β-dialkylamino and β-aziridino acrylamides have been synthesized and their configuration and conformation established by means of NMR and IR. Cis and trans isomers have been isolated in some cases, and their respective π → π* absorption maxima assigned. Configuration does not appreciably affect the frequency of this transition.
