In an article, author is Qiu, Shanguang, once mentioned the application of 123-06-8, Quality Control of Ethoxymethylenemalononitrile, Name is Ethoxymethylenemalononitrile, molecular formula is C6H6N2O, molecular weight is 122.1246, MDL number is MFCD00001854, category is nitriles-buliding-blocks. Now introduce a scientific discovery about this category.
Potassium tert-Butoxide Promoted Synthesis of 4,5-Diaryl-2H-1,2,3-triazoles from Tosylhydrazones and Nitriles
Intermolecular cycloaddition of tosylhydrazones with nitriles was investigated.t-BuOK was shown to be an excellent base for increasing the effectiveness of the reaction in this protocol, and homocoupling of the tosylhydrazones was significantly inhibited by using xylene as a solvent. Through this transformation, a variety of 4,5-diaryl-2H-1,2,3-triazoles were prepared in good to excellent yields and with high purities. The process is azide-free and transition-metal-free.
