Abstract

A practical aerobic oxidation of propargylic alcohols using Fe(NO3)3⋅9H2O, TEMPO and sodium chloride in toluene at room temperature was applied to various type of propargylic alcohols affording α,β-unsaturated alkynals or alkynones in good to excellent yields. This protocol could be applied in academic laboratories as well as in industrial-scale production.
