18. 2O-(DMF (2:1) solvent at 100°C because the Pt-N(pyridine) bond is kinetically labile around 100°C. The Pt(II)-catenane 5 shows clear ICD similar to that of Pd(II) containing catenanes.
19. The conformation of the Pt(II)-linked ring seems more rigid than that of the Pd(II)-linked ring because of the stronger coordination field of the Pt center. Due to the rigidity of the ring, the intensity of ICD of 3* is lower than that of 4*.
