Self-templated btp [2]catenane

Many congratulations to Joseph P. Byrne, Salvador Blasco, Anna B. Aletti and Gary Hessman on their publication “Formation of Self-Templated 2,6-Bis(1,2,3-triazol-4-yl)pyridine [2]Catenanes by Triazolyl Hydrogen Bonding: Selective Anion Hosts for Phosphate” that has been accepted for publication in the prestigious chemistry journal Angewandte Chemie.

 

 

Abstract: We report the remarkable ability of 2,6-bis(1,2,3-triazol-4-yl)pyridine (btp) compounds with appended olefin amide arms (2) to self-template the formation of interlocked [2]catenane structures (3) in yields of up to 50% when subjected to olefin ring-closing metathesis in CH2Cl2. X-ray diffraction crystallography allowed structural characterisation of both the [2]catenane 3a and the non-interlocked macrocycle 4a. These [2]catenanes show selective triazolyl hydrogen bonding interactions with the tetrahedral phosphate anion when screened against a range of ions; 3a and b being the first examples of selective [2]catenane hosts for phosphate.
