By introducing photoactive fac-tris(2-phenylpyridine)iridium moieties as a ligand backbone to constrain the coordination geometry of cobalt ions, a multifunctional Ir2Co3-type capsule was achieved and showed induced-fit capsule-capsule conversion by cooperative binding one carbonate anion with the equatorial Co(ii) centers. The capsule combined photocatalysis and transition metal activation synergistically and exhibited efficient catalytic ability on visible light-activated α-trichloromethylation.

4-Chloro-2-(1-hydroxybenzyl)pyridine and 4-chloro-2-(1-hydroxyalkyl)pyridines were obtained with moderate to excellent enantiomeric excesses and high isolated yields by bioreduction with Baker's yeast of the corresponding ketones. The resulting optically active alcohols were transformed into adequate DMAP derivatives, which have been applied in asymmetric catalytic processes as nucleophilic catalysts in the stereoselective chemical alkoxycarbonylation of 1-phenylethanol or as chiral ligands in the enantioselective addition of diethylzinc to benzaldehyde.
