The copper-promoted oxidative dehydrogenation and inner ring rearrangement of a macrocyclic ligand: the X-ray crystal structure of the resultant complex
Abstract
The (7 + 12 + 7) inner ring system of a polycyclic Schiff base rearranges with accompanying oxidative dehydrogenation to a (15 + 6 + 3) inner ring system on reaction with Cu(ClO4)2.6H2O in the presence of dioxygen in order to accommodate the CuII ion within the 15-membered ring.
