ABSTRACT
Ab initio calculations have been performed in order to investigate the conformational characteristics of p-
(nitro)methoxycalix[4]arene and p-(terl-butyl)methoxycalix[4]arene. The structures of four types (cone, parlial cone,
1,2-altemate and 1,3-altemate) of conformers for each compound have been optimized byab initio method at the
restricted Meller-Plesset fourlh-order perlurbatlon (RMP4) level of theory using 6-311G and 6-311G++(d,p) basis
sets. General trends in relative stabilities of p-(nitro)methoxycalix[4]arene and p-(terl-butyl)methoxycalix[4]arene are
similar and decrease in following order: parlial cone> cone> 1,3-altemate > 1,2-altemate. The calculated results of
the most stable conformation of parlial cone structure agree with.the reporled NMR experimental observations. |
