  found to be highly active for carrying out these reactions between aryl bromides and organoboron reagents. Further, the scope of the catalyst I was also examined by employing (hetero)aryl bromides, hydrophilic aryl bromides, benzyl bromides and various organoboron reagents. More than 80 aryl/benzyl bromide-arylboronic acid combinations were screened in neat water/K2CO3 and found that I is a versatile catalyst

  palladium-catalyzed Suzuki cross-coupling of benzyl ammonium triflates via activation of a Csp3–N bond to construct a Csp3–Csp2 bond is described. Various boronic acids can be coupled with a range of benzylamine-derived quaternary ammonium salts in 1:1 molar ratio by the bench-stable N-heterocyclic carbene palladium complex, SIPr-PdCl2-Py to afford diarylmethane derivatives. This reaction exhibits a wide
