Templated versus non-templated synthesis of benzo-21-crown-7 and the influence of substituents on its complexing properties
Two procedures for the synthesis of benzo-21-crown-7 have been explored. The [1+1] macrocyclization with KBF(4) as the template was found to be more efficient than the intramolecular macrocyclization without template. Pseudorotaxanes form with secondary ammonium ions bearing at least one alkyl chain...
