Rapid and Mild Deoxygenation of Sulfoxides with MoCl5/Gallium System under Ultrasonication

Abstract

However, many of these transformations often suffer from serious disadvantages, such as functional group incompati-bility, difficult work-up procedures, or harsh reaction condi-tions. Further some of these methods are associated with limi-tations regarding low yields and long reaction times. Therefore, there still exists a search for new improved methods. Particularly much effort has been devoted to the development of milder conditions where the presence of various sensitive and reducible functional groups can be tolerated. The use of low valent oxophilic d-block metals have become impo rtant in deoxygena-tion of various types of organic substrates.
