Perumal Rajakumaraand Ramar Padmanabhanb Synthesis, characterization and complexation studies of some novel cyclophane amides and sulfonamides[J] Tetrahedron Letters Volume 51, Issue 7, Pages 999-1130 (17 February 2010) a Department of Organic Chemistry, University of Madras, Guindy Campus, Chennai 600 025, India b Research and Development Centre, Orchid Chemicals and Pharmaceuticals Ltd, Sholinganallure, Chennai 600 119, India Abstract A series of tricyclic tetraamides have been synthesized and were characterized from spectral and XRD studies. XRD studies revealed that the pyridine-based tricyclic cyclophane amide exists with twisted phenyl rings. All the cyclophane compounds form charge-transfer (CT) complexes with TCNQ. Metal ion complexation studies show that the cyclophane amides are more selective towards Cu(II) ions rather than Ni(II) and Cd(II) ions.
