Substrate selectivity in the alkyne hydration mediated by NHC-Au(I) controlled by encapsulation of the catalyst within a hydrogen bonded hexameric host

Significant alterations in the substrate selectivity in the alkyne hydration reaction catalyzed by NHC-Au(I) 1 are observed as a consequence of encapsulation of the homogeneous catalyst within a hexameric resorcin[4] arene based hydrogen bonded self-assembled host.
