资源简介:
Oxacalixarenes
bearing acetylene groups are synthesized in a single
step by nucleophilic aromatic substitution reactions of orcinol with
various 1,5-diethynyl-2,4-difluorobenzenes. Thermodynamic equilibration
of the cyclooligomer mixtures was accomplished for arylethynyl activating
groups, leading to increased yields of the corresponding oxacalix[4]arenes.
A 1,3-alternate macrocycle conformation is observed in the solid state,
presenting a large V-shaped π-surface.
