A series of water‐soluble encapsulated copper(I), silver(I) or gold(I) complexes based on NHC‐capped permethylated cyclodextrins (ICyDMe) were developed and used as catalysts in pure water for hydration, lactonization, hydroarylation and cycloisomerizationreactions. ICyDMe ligands gave cavity‐based high regioselectivity in hydroarylations, and high enantioselectivities in gold‐catalyzed cycloisomerizations

A latent fluorophore (1) was rationally designed to give rise to strong fluorescence through a selective gold ion-mediated hydroarylation reaction by a catalytic amount of the gold(III) ion. It is a highly selective and sensitive fluorescence turn-on probe for gold(III) ions and is operative even in protic solvents.
