Decarboxylation of an alpha-amino acid coordinated to cobalt(III): kineticstabilisation and molecular structure of a Co-C-N three-membered ring incorporated into a cobalt(III) macrocyclic ligand complex

Photochemically-induced decarboxylation of a cobalt(III) cyclam complex bea ring two coordinated N-carboxymethyl pendant arms results in kinetic stabil isation of the resulting aminoalkyl three-membered Co-C-N ring, which has b een characterised by an X-ray crystal structure determination.
