Abstract
Application of molecular mechanics enabled calculation of the rotation al barrier between the two atropisomers of 2,3,5',6-tetramethyl-2'-(2- butyl)biphenyl The calculated energy barrier, 149.4 kJ/mol, is in good agreement with the experimental value of 155 kJ/mol reported by Koopm ans et al. (1996) for a similar 2,3,5',6-tetramethyl-2'-(2-alkyl)biphe nyl compound, supporting their interpretation of the GC-MS data of the se compounds. Copyright (C) 1996 Elsevier Science Ltd.
