A novel acenaphthoimidazolyidene oxazolinic palladium complex and its efficient catalysis in Suzuki-Miyaura cross-coupling reactions of -acyl-glutarimides N-C cleavage.

Herein, we synthesized a new Pd-N-heterocyclic carbene (Pd-NHC) complex that featured an acenaphthoimidazolylidene (AnIm) skeleton and 2-phenyl-2-oxazoline. This catalyst exhibited extremely high efficiency in Suzuki-Miyaura couplings between -acyl-glutarimides and organoboronic acids, affording various aryl ketones in excellent yields with a broad substrate scope and wide functional group compatibility. Notably, the reactions were completed in just 5 hours with only 0.
