1,3-二苄基脲 反应生成异氰酸苄酯 参考文献:Method For Making Carbamates,Ureas And Isocyanates 标题:Method For Making Carbamates,Ureas And Isocyanates 摘要:本发明提供了形成氨基甲酸酯,脲和异氰酸酯的方法.在某些实施方式中,这些方法包括将胺与酯基取代的二芳基碳酸酯反应,形成活化的氨基甲酸酯,进而可以进一步衍生为非活化的氨基甲酸酯或脲.脲或氨基甲酸酯可以经过热解反应形成异氰酸酯.
参考标题:1-Propanephosphonic Acid Cyclic Anhydride (T3P) As An Efficient Promoter For The Lossen Rearrangement: Application To The Synthesis Of Urea And Carbamate Derivatives 作者:Vommina Sureshbabu,Basavalingappa Vasantha,Hosahalli Hemantha |发布日期:2010.9 摘要:The Synthesis Of Hydroxamic Acids Starting From Carboxylic Acids Employing 1-Propanephosphonic Acid Cyclic Anhydride (T3P) Activation Is Described. Application Of Ultrasonication Accelerates This Conversion. Further, The T3P Has Also Been Employed To Activate The Hydroxamates, Leading To Isocyanates Via The Lossen Rearrangement. The Isocyanates Were Trapped With Suitable Nucleophiles To Afford The
