  • Etude spectroscopique quantitative de l'ecart a la planeite du systeme conjugue dans les molecules d'α-enones R1COCR2CH2
    作者:A. Bienvenue
    DOI:10.1016/0040-4020(72)84043-2
    日期:1972.1
    UV, NMR and IR spectra of 9 αβ-unsaturated ketones R1COCR2CH2 have been studied, where R1 and R2 are Me, Et, i-Pr, t-Bu or neo-Pe groups. UV and especially IR spectroscopy give more useful information than NMR spectroscopy. When R1 = Me, Et, i-Pr or t-Bu and R2 = Me, an equilibrium exists between the s-trans and a twisted conformation in which the diedral angle between the two π systems is about 120°
