Unusual reactivity of copper(I) complexes of functionalised calix[4]arenes

摘要

Two functionalised calix[4]arenes, 5,11,17,23-tetra-tert-butyl-25,27-bis(2-pyridylmethoxy)calix[4]arene (L) and 5,11,17,23-tetratert-butyl-25,27-bis(2-pyridylmethoxy)-26,28-dibutoxycalix[4]arene (L-3), were prepared and characterised. The copper(I) complexes of both calix[4]arenes were synthesised and their reactivities were analysed and compared. The presence of the metal induced a radical in the case of L-1 whereas no such radical was observed in the metal complex of ligand L. (c) 2005 Elsevier B.V. All rights reserved.
