Synthesis, Characterization, and Reactivity of "Reverse Pyridine" Bis(phosphinite) Pincer Complexes


Swisher, Nicholas Adam (2019) Synthesis, Characterization, and Reactivity of "Reverse Pyridine" Bis(phosphinite) Pincer Complexes. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/S8YH-QR85.


In chapter 1 the synthesis of several pincer complexes based on a "reverse pyridine" bis(phosphinite) ligand motif is described. Coordination of a borane Lewis acid to the parent ligand is described, as well as factors influencing the subsequent metalation of both the "free base" ligand and borane-adduct ligand. The effect of Lewis acid coordination on the spectroscopic and electrochemical properties of the resulting metal complexes is discussed. The reversibility of Lewis acid binding for some complexes is also described.

In chapter 2, an unusual method for carbon-oxygen and carbon-sulfur bond cleavage mediated by alkoxide salts and using silanes as reductants is described.
