Abstract
m- or p-phenylenediamine and m- or p-chlorophenyl-substituted azacrown ether derivatives were synthesized through sequential nucleophilic substitution of [(η5-cyclopentadienyl)(η6-(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.
