Atomically precise ultrasmall copper cluster for room-temperature highly regioselective dehydrogenative coupling.

ABSTRACT: Three-component dehydrogenative coupling reactions represent important and practical methodologies for forging new C-N bonds and C-C bonds. Achieving highly all-in-one dehydrogenative coupling functionalization by a single catalytic system remains a great challenge. Herein, we develop a rigid-flexible-coupled copper cluster [Cu₃(NHC)₃(PF₆)₃] (Cu₃NC^(NHC)) using a tridentate N-heterocyclic carbene ligand. The shell ligand endows Cu₃NC^(NHC) with dual attributes, including rigidity and flexibility, to improve activity and stability. The Cu₃NC^(NHC) is applied to catalyze both highly all-in-one dehydrogenative coupling transformations. Mechanistic studies and density functional theory il
