Abstract
Abstract The 1H and 13C nuclear magnetic resonance spectra of N2 ,N 4,N6 -triphenethyl-1,3,5-triazine-2,4,6-triamine show features that suggest the hindered rotation about the carbon-nitrogen bond. A dynamic experiment was conducted at variable temperatures to determine the rotational barrier around this bond, which was also theoretically calculated and corroborated by density functional theory. X-ray diffraction analysis confirmed the compound structure and revealed the carbon-nitrogen partial double bond character, responsible for the restricted rotation. The infrared spectrum showed the characteristic bands, as expected. Finally, the cytotoxicity of this compound was evaluated in vitro against a human hepatocellular carcinoma cell line and exhibited a good antiproliferative action.
