Bis(phosphine) Pd(II)–azido complexes containing heterocyclic ligands: Reactivity toward organic isocyanides

Bis(phosphine) Pd–azido complexes containing heterocycles such as tetrazolyl, pyrazinyl, and thienyl groups reacted with aryl isocyanides to give the corresponding Pd–carbodiimido or –imidoyl carbodiimido complexes. These products were formed by the insertion of the isocyanides into the Pd–N (azido) or the Pd–C (heterocycles) bond.
