参考标题:Coupling Of Trifluoroacetaldehyde N-Triftosylhydrazone With Organoboronic Acids For The Synthesis Of Gem-Difluoroalkenes 作者:Yu Ma,Bhoomireddy Rajendra Prasad Reddy,Xihe Bi |发布日期:2019.12.20 摘要:Synthesis Of Alkyl Gem-Difluoroalkenes Remains A Difficult Task In Organic Synthesis. Here, We Report A General And Efficient Approach For Tackling This Problem By Gem-Difluoroolefination Of Trifluoroacetaldehyde N-Triftosylhydrazone With Organoboronic Acids. This Protocol Is Operationally Simple, Free Of Transition Metals, And Suitable For A Broad Range Of Organoboronic Acids. Moreover, The Utility
