Counteranion-Controlled Ag<sub>2</sub>O‑Mediated Benzimidazolium Ring Opening and Its Application in the Synthesis of Palladium Pincer-Type Complexes
We
report a new approach to synthesize palladium complexes through Ag<sub>2</sub>O-promoted hydrolytic ring opening followed by palladium coordination.
The novelty of Ag<sub>2</sub>O-promoted hydrolysis in comparison with
the commonly used base-mediated hydrolysis lies in the anion-controlled
product selectivity in the synthesis of pincer-type palladium complexes.
Moreover, these palladium complexes have been tested in the Suzuki
reaction using aryl bromides in methanol and H<sub>2</sub>O, respectively.
In comparison with palladium complexes with normal coordination, the
palladium complexes generated from the hydrolytic ring-opening coordination
demonstrate excellent catalytic activity
