  Ru(III)-catalyzed oxidation of homopropargyl alcohols in ionic liquid: an efficient and green route to 1,2-allenic ketones

  摘要：

  An efficient and environmentally benign synthesis of 1,2-allenic ketones via RuCl(3)-catalyzed oxidation of homopropargyl alcohols in ionic liquid with tert-butyl hydroperoxide (TBHP) as the oxidant was reported for the first time. With its reasonable efficiency and green nature, this oxidation provides a novel alternative route to 1,2-allenic ketones. (c) 2010 Elsevier Ltd. All rights reserved.

  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.
