Cationic palladium catalysts comprising diamino carbene ligands, wherein the catalysts are of the formula [Pd(X)q(LBX)t(DC)]r+[Ym-]p or [Pd(X)q(LB)n(LBX)t(DC)]2a+[V-]u[Z2-]y, wherein DC is a diamino carbene ligand, X is an anionic ligand, LBX is a combined anionic and neutral ligand, and Y, V, and Z are non-coordinating anions. The compounds are useful in catalytic reactions, including cross-coupling reactions and hydroamination reactions. In particular, the catalysts are used in the following reactions: Suzuki-Miyaura coupling, Kumada coupling, Negishi coupling, Sonogashira coupling, Hartwig-Buchwald amination, and Heck-Mizoroki coupling.
