《Synthesis and structure of dialkyl (Z)-3-amino-2-cyano-4-diazopent-2-enedioates》 was published in Monatshefte fuer Chemie in 2020. These research results belong to Yavari, Issa; Mohsenzadeh, Ramin; Kayanian, Jasmine. Formula: C9H7NO The article mentions the following:
Diazo-transfer reaction of tosyl azide and alkyl 2-cyanoacetates in the presence of pyridine at 0° gives the corresponding alkyl 2-cyano-2-diazoacetates. This material readily underwent nucleophilic attack by pyridinium 1-cyano-2-alkoxy-2-oxoethan-1-ide to form dialkyl (Z)-3-amino-2-cyano-4-diazopent-2-enedioates. The X-ray structure of a typical product is reported, as well as DFT computational studies that illuminate the structural features of these stable diazo compounds The results came from multiple reactions, including the reaction of 3-Oxo-3-phenylpropanenitrile(cas: 614-16-4Formula: C9H7NO)
3-Oxo-3-phenylpropanenitrile(cas: 614-16-4) has been used to produce 2-benzoyl-3-furan-2-yl-acrylonitrile. It is an active methylene compound, useful in heterocyclic synthesis, e.g. polyfunctional pyridines and pyrimidines.Formula: C9H7NO
