Novel single precursors for Ni, Ni(dmamp)2 (1), Ni(deamp) 2 (2), and Ni(emamp)2 (3), were synthesized by the metathesis reaction between [Ni(NH3)6]Cl2 and two equiv. of Na(dmamp), Na(deamp), and Na(emamp), respectively. Complexes 1-3 have been characterized by IR, 1H NMR, and 13C NMR spectroscopies, and microanalytical data, as well as single-crystal X-ray diffraction studies. Through GC/MS analysis of the gaseous species generated by the decomposition of 1, a self-reduction pathway to form metallic Ni was studied. By the metalorganic chemical vapor deposition of 1, metallic Ni hexagonal-phase thin films were obtained at 250 °C and cubic-phase thin films were obtained at 400 °C.
Reaction des amines secondaires avec les aldehydes α,β-dibromes. Preparation d'α,β-diaminoaldehydes derives du cinnamaldehyde et nouvelle voie d'acces aux diamino-1,2 ethylenes

Secondary amines react with α-bromocinnamaldehyde to yield various 2,3-bisdialkylamino-3-phenylpropanals.These diaminoaldehydes undergo two competitive rections respectively leading to α-aminocinnamaldehyde and 1,2-diamino-ethylene.Experimental conditions selectively yielding one of these compound have been studied.With 2,3-dibromobutanal the same reaction does not afford diaminoaldehyde but 1,2-diaminoethylene and a new compound, 1,2,3-triamino-1-butene.A possible reaction mechanism is discussed and a new, general one-pot synthesis of 1,2-diaminoethylene from 2-butenal with good yields is described.
