Abstract
The tetra(ferrocene)-cyclam macrocycle 1,4,8,11-tetra(ferrocenylmethyl)-1,4,8,11-tetraazacyclotetradecane (L) and two corresponding CuI and CuII complexes have been prepared and characterized from spectroscopic and electrochemical studies (cyclic voltammetry and rotating disk electrode experiments). Both complexes exist under two energetically distinct geometries which differ mainly from the relative positionning of the ferrocenylmethyl groups above or below the macrocyclic plane and it is shown that a reversible change from one geometry to the other can be electrochemically induced following a copper-centered electron transfer. The equilibrium constants, mechanisms and kinetic parameters of these rearrangements have been evaluated using electrochemical simulation.
