On August 26, 2022, Joseph, Devaneyan; Lee, Sunwoo published an article.Application In Synthesis of 1,3-Diphenylurea The title of the article was Reaction of Amide and Sodium Azide for the Synthesis of Acyl Azide, Urea, and Iminophosphorane. And the article contained the following:
Amides reacted with NaN3 to give the acyl azides in DMF at 25°C and produce the sym. ureas in THF/H2O at 80°C via the sequential reaction of acyl substitution and Curtius rearrangement. All acyl azides were also obtained from the secondary amides via sequential reaction of p-toluenesulfonyl chloride and NaN3. In addition, keto-stabilized iminophosphoranes were prepared from a one-pot reaction of amides, NaN3, and phosphines. The experimental process involved the reaction of 1,3-Diphenylurea(cas: 102-07-8).Application In Synthesis of 1,3-Diphenylurea
The Article related to acyl azide sym aromatic urea iminophosphorane preparation, amide sodium azide phosphine substitution curtius rearrangement, Benzene, Its Derivatives, and Condensed Benzenoid Compounds: Ureas, Carbamic Acids, Guanidines, and Their Sulfur-Containing Analogs and other aspects.Application In Synthesis of 1,3-Diphenylurea
