Thermal reactions of 2-hydroxymethylpyridine (HMP) with [M(CO)6] in air resulted in formation of the oxo-complexes [M2O6(HMP)2], where M = Mo, 1, or W, 2. The tricarbonyl complex [Ru(CO)3(HMP)], 3, was obtained from the reaction of [Ru3(CO)12] with HMP. In presence of triphenyl phosphine (PPh3), the reaction of HMP with Ru3(CO)12 gave [Ru(CO)2(HMP)(PPh3)], 4. All the complexes were characterized by elemental analysis, mass spectrometry, IR, and NMR spectroscopy. The thermal properties of the complexes were also investigated by thermogravimetry technique.

ABSTRACTDerivatives of 2,6-bis(4-azidobenzylidene) cyclohexanone are frequently used as photosensitizers in photoresists. These compounds are generally considered to be quite thermally stable. However, there have been reports of thermal degradation occurring at temperatures as low as 60'C.Experiments done here suggest that the thermal stability of the azide is adversely affected by the presence of unsaturated material in the formulation. Data from IR spectroscopy show that, by itself, 2,6-bis(4-azidobenzylidene) 4-methylcyclohexanone is thermally stable in a polyamic acid film at 75–80° C. However, addition of a monomeric aminoacrylate to the formulation results in a significant decay in the absorption of the azide moiety in just a few hours at these same temperatures. This decay is attributed to reaction of the sensitizer with the acrylate double bonds. In a thick film, which might require a 1–2 hour prebake, this thermal addition could result in a significant degree of crosslinking and thus to decreased contrast in the final pattern.
