Name: 4-FluorobenzonitrileIn 2021 ,《4,4′-(Pyridin-4-ylmethylene)dibenzonitrile》 appeared in Molbank. The author of the article were Lancaster, Ben M. J.; Nicholls, Alexander J.; Baxendale, Ian R.. The article conveys some information:
This communication described an unprecedented substitution cascade, in which 4-methylpyridine, following deprotonation with LDA, twice acted as a carbon nucleophile in an unusual SNAr process, to form a novel triarylmethane structure I. A proposed mechanism for this sequence was presented that was supported by single crystal X-ray anal. of the resulting product. This unique transformation was of note as it highlighted a neat and efficient entry as a single step to complex triarylmethane architectures containing both substituted Ph and pyridyl aromatics The experimental process involved the reaction of 4-Fluorobenzonitrile(cas: 1194-02-1Name: 4-Fluorobenzonitrile)
4-Fluorobenzonitrile(cas: 1194-02-1) is used as chemical intermediate, solvent for perfumes and pharmaceuticals, stabilizer for chlorinated solvents, HPLC analysis, catalyst and component of transition-metal complex catalysts.Name: 4-Fluorobenzonitrile
