carbene C,S palladium(II) π-allylcomplexes were successfully developed and characterized. Structural analyses of these complexes revealed that the organopalladium chelates adopt a skew-envelope conformation with a trans disposition of the substituents on the metal chelate rings. Utilizing these C,S palladium(II) π-allylcomplexes as catalysts, a catalytic system for the allylic amination reaction has
