ABSTRACT
A series of novel triazinonide-bridged bisimidazolium pincers were easily synthesized by quaternization of functionalized N-phenylimidazoles with highly reactive cyanuric chloride under mild conditions. The pincer was proven to be a very efficient ligand for in situ Pd-catalyzed Suzuki-Miyaura reaction with ppm-level catalyst loading.
