Reactivity of alkynyl Pd(II) azido complexes toward organic isocyanides, isothiocyanates, and nitriles

Reactions of alkynyl Pd(II) azido complexes, Pd(N3)(CCR)L2, with organic isocyanides, isothiocyanates, and nitriles afforded new Pd(II) complexes containing five-membered heterocycles (C- or N-coordinated tetrazolato or tetrazole-thiolato), carbodiimido (NCNR), and cyano groups, depending on the organic substrates.
