Design of unsaturated hydride metal complexes and study of their reactivity toward small molecules.

Design of unsaturated hydride metal complexes and study of their reactivity toward small molecules. - 234 p.

Adviser: Kenneth G. Caulton.

Thesis (Ph.D.)--Indiana University, 2006.

Due to potential application in various chemical processes, the design of electronically and coordinatively unsaturated metal complexes are of high interest. These unsaturated compounds could not only be applied to cleave or make strong bonds (C-H, C-C, Si-H, C-F) but also activate unreactive gas molecules (CO, N2O, H2, N2) so that easier transformation into organic molecules may be allowed.

520 $a Due to potential application in various chemical processes, the design of electronically and coordinatively unsaturated metal complexes are of high interest. These unsaturated compounds could not only be applied to cleave or make strong bonds (C-H, C-C, Si-H, C-F) but also activate unreactive gas molecules (CO, N2O, H2, N2) so that easier transformation into organic molecules may be allowed.
520 $a This work investigates the synthesis and reactivity of designed unsaturated metals (especially Ru or Os) which are identified by combining of various methods (multi-nuclear NMR, Infrared, X-ray diffraction and DFT). However, the stability of the highly reactive metal compounds is very low. Therefore to stabilize electronically or coordinatively deficient metal compounds, two bulky alkylphosphines have been applied to the metal system. Bulky phosphine moiety can support a low coordination number on the monomeric metal complex, as well as avoid having interaction between each other. In addition, strong electron donation from these phosphines to metal allows the synthesis of these low valence electron count metal complexes and to explore their reactivity toward various substrates. Here, the reactivity of Os or Ru alkyl phosphine complexes toward alkynes or radical NO gas has been explored. One example of this study shows dimerization or polymerization of alkyne.
520 $a In addition, a bulky alkylphosphino amido is applied in this study. This bulky ligand system supports formation of monomeric metal species due to steric bulk imposed by the alkylphosphine moiety. Lone pair electron donation by ligand nitrogen also facilitates low valence electron compounds. The Os metal system has been mainly studied here. Reactivity of metal complexes with alkyne or gases (H2, CO, N2O, or NO) has been developed. As one of surprising example of study with this ligand system, it has been found that the metal compound can convert N2O to H2O and N 2.
