Hussein, Ahmad Q.; Sammor, Mervat S. published their research in Heterocyclic Letters in 2021. The article was titled 《New easy one-pot synthetic routes of 2-arylbenzimidazoles》.Synthetic Route of C9H7NO The article contains the following contents:
One-pot condensation of 1,2-phenylenediamine with phenacyl cyanides affords high yields of the corresponding 2-arylbenzimidazoles. The same products are also obtained through similar condensation of phenylenediamine either with phenacyl thiocyanates or with benzylidenemalononitriles. In the experimental materials used by the author, we found 3-Oxo-3-phenylpropanenitrile(cas: 614-16-4Synthetic Route of 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.Synthetic Route of C9H7NO
