First clathrochelate iron and cobalt(II) tris-dioximates with reactive apical substituents
摘要:
Direct template macrobicyclization of three 1,2-cyclohexanedione dioxime molecules with monofunctionalized HO-, H2N- and HOOC-containing phenylboronic acids on Fe2+ and Co2+ ions as a matrix afforded new macrobicyclic iron and cobalt(II) tris-dioximates with reactive apical substituents. The clathrochelates synthesized has been characterized by spectroscopic methods, X-ray crystallography and cyclic voltammetry. (C) 2013 Elsevier B.V. All rights reserved.
