Synthesis of 1,2-allenic ketones through oxidation of homopropargyl alcohols with CrO3(cat.)/TBHP under MWI

A CrO3 catalyzed oxidation of homopropargyl alcohols with tert-butyl hydroperoxide under microwave irradiation was found to be an efficient and rapid alternative for the preparation of 1,2-allenic ketones. The advantages of this procedure include short reaction time, less adverse impact on the environment and reasonably high efficiency.
