The most common catalyst is palladium, but an increasing number of reactions use nickel.Other catalysts include copper, platinum, iron, cobalt, and amines.. Palladium is robust catalyst and is frequently used due to high functional group tolerance, and low sensitivity of organopalladium compounds towards water and air. However, palladium is a quite rare and costly noble metal.
