Isolation of a copper photocatalyst on a metal–organic cage for the sulfonylation of aryl halides resulting from visible-light-mediated C(sp2)–S cross-coupling†
Abstract
A Ce-based metal–organic tetrahedron was assembled for preserving the uncoordinated nature of 2,2′-bipyridyl groups to form a Cu-based photocatalyst, which protected CuI centers from intermolecular deactivation and showed high photocatalytic activity for the visible-light-mediated C(sp²)−S cross-coupling.
