Wrapper's delight : Clathrochelate complexes, in which the metal center is wrapped in a close‐knit macrobicyclic ligand, are often considered to be deprived of chemical reactivity. Boron‐capped cobalt tris(glyoximato) complexes show catalytic activity in the reduction of acids in acetonitrile at potentials as small as −0.5 V versus SCE. Alteration of ligand substituents allows for the tuning of their electrochemical reactivity (see structure: red ball Co, grey C, purple B, blue N, red O, green X).
