Abstract

Through the use of template condensation reactions, we have developed synthetic routes to a number of fluorinated ligands containing a number of donor atoms in combination with a fluorinated alkoxy group. Typical examples are: ▪ We find all of these to be capable of coordination to transition metals, generally giving stable, neutral, complexes. However, the mode of coordination of (i) and (ii) differs according to the donor atoms present in the chain, with a higher degree of coordination for X = N than for X = O. With ligand (iii), a ‘tripod’ mode of coordination is favoured, with the six donor sites surrounding a 3+ metal ion such as iron(III), cobalt(III), or a lanthanide(III) species.
