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.
