Abstract
Chapter 1. The synthesis and resolution of sterically encumbered biphenols is presented. -- Chapter 2. The synthesis of molybdenum(VI) imido alkylidene complexes containing racemic and optically pure biphenoxides (Biphen and Biad) is reported. -- Chapter 3. The 1H NMR spectroscopic data for molybdenum(VI) imido alkylidene biphenoxide complexes prepared in Chapter 2 are presented. -- Chapter 4. The application of catalysts prepared in Chapter 2 in asymmetric ring-closing metathesis (ARCM) is described. -- Chapter 5. Synthesis, characterization and reactivity of (±)(Me2)W(Neo) and (±)(iPr 2)W(Neo) . PMe2Ph is discussed.
