A robust hydrophilic pyridine-bridged bis-benzimidazolylidene palladium pincer complex: Synthesis and its catalytic application towards Suzuki-Miyaura couplings in aqueous solvents

A novel hydrophilic pyridine-bridged bis-benzimidazolylidene palladium pincer complex (3) acted as a highly efficient robust recyclable molecular catalyst towards Suzuki-Miyaura coupling reactions in aqueous media and tolerated various functional groups (even heterocycles) with extremely low catalyst loading.
