Incorporation of a Sugar Unit into a C-C-N Pincer Pd Complex Using Click Chemistry and Its Dynamic Behavior in Solution and Catalytic Ability toward the Suzuki-Miyaura Coupling in Water
A Pd complex With a pincer ligand constituted of two N-heterocyclic carbenes and a triazole moiety containing a sugar unit, which was incorporated using click chemistry, was synthesized. Two diastereomers of the complex, which were in equilibrium, were observed in solution. The complex worked as a catalyst for the Suzuki-Miyaura cross-coupling reaction in aqueous media showing a turnover number of up to 76000.
