Dynamics of Atropisomerization of 1,1'-Binaphtyl in Several Nematic Solvents. Rate Enhancement by a Solid Phase

Article abstract of DOI:10.1021/ja00248a036

The rates of atropisomerization of (S)-1,1'-binaphtyl (BN) are compared in six nematic phases and in the solid phase of p-methoxybenzylidene-p-n-butylaniline.The influence of each phase on the activation parameters for atropisomerization are correlated with the solvent molecular structures.The results in the nematic and solid phases are interpreted in terms of degree to which the solvent matrices flatten the angle between the naphtyl rings of BN.
