New N₂O₂‐ and N₂O₃‐Macrocycle Ligands Incorporating p‐Xylyl Groups

Abstract

The synthesis and characterization of four dibenzo‐substituted macrocycles incorporating mixed nitrogen and oxygen heteroatoms as well as one or two xylyl groups are reported. The X‐ray structure of one product containing two xylyl functions is presented.

Keywords:

• Macrocycle
• Synthesis
• X‐ray structure
