Abstract: A highly chemically stable primary amide-functionalized cyclotricatechylene covalent organic framework was synthesized by an irreversible reaction and a postsynthetic modification. It possessed a rod-like morphology and exhibited strong solvent stability owing to the polyether bonds.… read more here.

Abstract: Herein, we report ruthenium(II)-catalyzed weakly coordinating primary amide-assisted ortho-di-alkynylation of (hetero)arylamides via double C-H bond activation in the presence of bromo-alkynes as coupling partners. The attractive features of the developed strategy lie in the usage… read more here.
