title: Preparation of N-aryl azacrown ether derivatives, using arene-iron chemistry.
abstract: m- or p-phenylenediamine and m- or p-chlorophenyl-substituted azacrown ether derivatives were synthesized through sequential nucleophilic substitution of [(eta(5)-cyclopentadienyl)(eta(6)-(m- or p-dichlorobenzene))]iron hexafluorophosphate by azacrown ethers and cyclohexaamines. Monoarylation is the main reaction for diazacrown ethers. The overall yield from the starting complex is 50-96% for multiple steps.
