Intramolecular three-centered hydrogen bonding has been used to induce dipyridyl anthranilamide 5 and diphenylacetylene anthranilamide 11 to adopt rigid straight conformation. Compound 5 reacted with Pd(dppp)(OTf)2 (12a) or Pt(dppp)(OTf)2 (12b) in dichloromethane to afford square metallocyclophanes 13a and 13b in 70% and 40% yield, respectively. In contrast, the reaction of 11 with 12b in dichloromethane gave triangular metallocyclophane 14 in 15% yield.
