Deoxydehydration of diols by d0 early-metal-oxo complexes.

by Kilyanek, Stefan M.

Molybdenum-dioxo complexes supported by a variety of ligands have been shown to perform deoxydehydration of vicinal diols to form alkenes in good yield at relatively mild temps. (<200 deg C). The scope of reductants and substrates for this conversion will be discussed. The reaction rates were investigated by in situ IR spectroscopy and the mechanism was probed by in situ IR and NMR spectroscopy. Addnl., the electrochem. redn. of these complexes and other deoxydehydration catalysts leads to the formation of disparate metal-oxo products.
