Late Transition Metal Complexes with Fluorinated Aryloxide and Alkoxide Ligands

High-oxidation state transition metal complexes are of sustained interest as targets for synthesis because of their important role in stoichiometric and catalytic bond activation processes.  To date work in this area has been dominated by nitrogen-atom donor ligands.  Our group is investigating oxygen donor ligand systems as an alternative.  The synthesis and reactivity of late transition metal homoleptic compounds of fluorinated alkoxide and aryloxide ligands will be presented.

Trianionic pincer ligands: nitrile synthesis via N-atom transfer, high oxidation state Cr(IV) and Cr(V) and new chemistry with W-W triple bonds

Trianionic pincer ligands: nitrile synthesis via N-atom transfer, high oxidation state Cr(IV) and Cr(V) and new chemistry with W-W triple bonds Dr. Adam S. Veige University of Florida Abstract: Classic pincer ligands (A, E = P, N, O, S) are complementary to late transition. Our approach is to match the harder early transition metals with a harder pincer ligand. We have synthesized a series of new pincer ligands based on amidoarylideamido (B, Ar = 2,6iPrC6H3, and 3,5MeC6H3) and alkoxidearylidealkoxide linkages (C, OCO3 = 1,3-C6H4(6-tBuC6H3OH)2).
