| Popis: | Infrared spectra of 2,2′-alkylidene, 2,2′-thiobisphenols, and 2,2′-biphenyldiols have been measured in the range of the OH stretching vibrations. From these measurements the possible conformers present in dilute CCl4 solutions are proposed. A correlation between the amount of the free and the intramolecularly bound hydroxyl groups in 2,2′-bisphenols and their antioxidative activity is discussed. |
