| Abstract: | The simple synthetic development of acyclic pincer bis(pyridine)carbodicarbene is depicted herein. Presented is the first isolated structural pincer carbodicarbene with a C‐C‐C angle of 143°, larger than the monodentate framework. More importantly, theoretical analysis showed that this carbodicarbene embodies a more allene‐like character. Palladium complexes supported by this pincer ligand are active catalysts for Heck–Mizoroki and Suzuki–Miyaura coupling reactions. |
