Tetra-azadiene-exchange and -rearrangement reactions have been observed for both and 5-C5H5)> (R2=1,4-diaryl) complexes.The reactions of or 5-C5H5)> with aryl azides lead to substitution of the tetra-azadiene ligands.Reactions of or 5-C5H5)> with aryl azides R'N3 produced platinium and nickel complexes with non-symmetrical RN4R' ligands.All products arising from these reactions were identified by field desorption mass spectrometry and/or h.p.l.c.Four mechanisms which can account for the nature of the observed products, the product distributions, and reaction times are discussed.Transient aryl-nitrene species are proposed as key intermediates in these reactions.
