Abstract

Two functionalised calix[4]arenes, 5,11,17,23-tetra-tert-butyl-25,27-bis(2- pyridylmethoxy)calix[4]arene (L¹) and 5,11,17,23-tetra-tert-butyl-25, 27-bis(2-pyridylmethoxy)-26,28-dibutoxycalix[4]arene (L³), 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 L¹ whereas no such radical was observed in the metal complex of ligand L³.
