Fund Project: We are grateful to the National Natural Science Foundation of China (Nos. 20772025 and 20972042), Innovation Scientists and Technicians Troop Construction Projects of Henan Province (No. 104100510019), Natural Science Foundation of Henan Province (No. 092300410237) and the Natural Science Foundation of Department of Education of Henan Province (Nos. 2009A150017 and 2008A150013).

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.
