Abstract
  • This dissertation focuses on investigations into the reactivity and regioselectivity of hydrocarbon C-H bond activation by Tp'Pt(IV) (Tp' = hydridotris(3,5- dimethylpyrazolyl)borate) reagents via (1) thermolysis, (2) Lewis acid addition, and (3) low temperature protonation reactions. Insertion of α-olefins into a Pt-H or Pt-Ph bond has been found to occur. The synthetic and mechanistic investigations of these insertion reactions provide a starting point toward the aim of hydrocarbon functionalization. Gentle heating of Tp'PtMe2H in alkane solvents in the presence of B(C6F5)3 results in C-H activation of the alkane solvent, R-H, to give Tp'Pt(Me)(H)(R) complexes. Further heating leads to formation of Tp'Pt(η2-olefin)(H) complexes via methane elimination followed by β-hydride elimination, a stoichiometric alkane to olefin conversion...
