Bis(acetonitrile)palladium dichloride

Bis(acetonitrile)palladium dichloride is the coordination complex with the formula PdCl₂(NCCH₃)₂. It is the adduct of two acetonitrile ligands with palladium(II) chloride. It is a yellow-brown solid that is soluble in organic solvents. The compound is a reagent and a catalyst for reactions that require soluble Pd(II).^[1] The compound is similar to bis(benzonitrile)palladium dichloride. It reacts with 1,5-cyclooctadiene to give dichloro(1,5-cyclooctadiene)palladium.
