Synthesis and Complex-Forming Properties of N-Substituted Diazacrown Ethers
摘要:
N-Substituted mono- and diazacrown ether with ethoxycarbonylmethyl, 7-phenyl-3,6-dioxaheptyl, p-methoxy, and p-nitrobenzyl groups in the side chain have been synthesized. Their reactions with alkali and alkaline-earth metals have been studied. Substituents affect the complex-forming ability of the "base" macrocycle by changing the basicity of the nitrogen atoms and coordinating with the complexing ion.
