Bond Character

The organophosphonous-N-(N′,N′,N″,N″-tetramethyl)guanidinide fluorides RP(F)N=C(NMe2)2 2a (R = t-Bu) and 2b (R = Ph) were synthesized. They are readily oxidized by the urea-H2O2 1:1 adduct and by elemental sulfur, selenium and tellurium to give the compounds 4a/b, 5a/b, 6a/b and 7a/b respectively. Compound 2b undergoes a Staudinger reaction with triphenylmethyl azide to yield the phosphine imide 3. The compounds were characterized by 1H-, 13C-, 19F and 31P NMR spectroscopy, and 6a/b and 7a/b by 77Se and 125Te NMR spectroscopy. The structures of the sulfur compound 5b and the selenium compound 6a were confirmed by X-ray crystal structure analysis. Both molecules exhibit short P-N-bonds [158.9(2) pm and 159.8(3) pm] consistent with partial double bond character even though the P(:S) and the P(:Se) bonds are not longer than a normal double bond.

The synthesis and characterization of Ti and TiN thin films of different thicknesses was carried out on a martensitic stainless steel AISI 410 substrate used for tool manufacturing. The mechanical parameters between the interacting surfaces such as thickness, adhesion and hardness were measured. By means of the scanning electron microscope (SEM) the superficial morphology of the Ti/TiN interface was observed, finding that the growth was of columnar grains and by means of EDAX the existence of titanium was verified.  Using X-ray diffraction (XRD) it was possible to observe the presence of residual stresses (~ -3.1 GPa) due to the different crystalline phases in the coating. Under X-ray photoemission spectroscopy (XPS) it was possible to observe the molecular chemical composition of the coating surface, being Ti-N, Ti-N-O and Ti-O the predominant ones.
