Bis(benzonitrile)palladium chloride, also known as PdCl2(C6H5CN)2, is a palladium complex widely used in organic synthesis as a catalyst. It consists of palladium (Pd) coordinated with two molecules of benzonitrile and two chloride ions. This complex is commonly employed in various cross-coupling reactions such as the Heck reaction and Suzuki-Miyaura coupling to form carbon-carbon bonds. Bis(benzonitrile)palladium chloride plays a crucial role in the development of new pharmaceuticals, agrochemicals, and materials due to its ability to facilitate challenging chemical transformations efficiently.
