Room temperature Fe(NO3)3.9H2O/TEMPO/NaCl-catalyzed aerobic oxidation of homopropargylic alcohols

A practical and eco-friendly aerobic oxidation of homopropargylic alcohols using Fe(NO3)(3).9H(2)O/TEMPO/NaCl as catalysts at room temperature under atmospheric pressure was developed affording corresponding homopropargylic ketones with moderate to good yields. Aryl, heteroaryl as well as alkyl 1,2-allenic ketones were obtained by the isomerization of corresponding terminal homopropargylic ketones through column chromatographic workup on silica gel.
