Реферат:
Properties and mechanisms of thermal and photo decomposition of ruthenium complexes [Ru(acac)2(tmp-mian)] (1) and [Ru(acac)2(tmp-bian)] (2) [where acac = acetylacetonate, tmp = 2,4,6-{CH3}3C6H2, mian is monoiminoacenaphtheneone, and bian is acenaphthene-1,2-diimine] in acetonitrile were studied in real time by aerodynamic thermal breakup droplet ionization mass spectrometry (ATBDI-MS). A comparison of the ATBDI-MS spectra of complexes 1 and 2 showed a difference between photolysis processes in these structurally similar complexes because the Ru–O– bond in complex 1 is much weaker than the Ru–Ndouble bond bond in complex 2. This difference leads to easier decomposition of complex 1 and facilitates the capture of solvent molecules by products of complex 1′s photolysis. Similarly, the analysis of thermal decomposition of complexes 1 and 2 at increasing temperatures of an ATBDI suction tube (Tsuction) showed that complex 1 is much more susceptible to thermal decomposition and starts to disintegrate already at 100 °C. Complex 2 is much stabler; there was no evidence of its thermal decomposition when Tsuction was raised up to 330 °C.
