Abstract

A new family of iron (III) sequestering agents has been designed. Tripodal ligands possessing six convergent hydroxyl groups have been prepared by condensation of an appropriate o, o'-biaryl building block and a spacer. The preparations of building blocks and of simple bidentate ligands designed for comparative studies are described: several methods have been used for ortho functionalisation and for 3, 3′-difunctionalisation of 2, ...
