General description

2-Iodophenylacetonitrile is a 2-aryl substituted nitrile. It reacts with lactams to form ring-fused isoquinolinones via palladium-catalyzed carboxamidation in tandem with aldol condensation.

Application

2-Iodophenylacetonitrile may be used in the preparation of:
  • 2?-aminobiphen-2-ylacetonitrile
  • ethyl (2-iodophenyl)iminoacetate hydrochloride
  • 3,4-disubstituted 2-naphthalenamines

It may also be used in the preparation of the following nitriles:
  • 2-(2-iodophenyl)-2-methylpropanenitrile
  • 1-(2-iodophenyl)cyclopentanecarbonitrile
  • 5-bromo-2-(2-iodophenyl)pentanenitrile
  • 2-(2-iodophenyl)-2-propylpentanenitrile
  • 1-(2-iodophenyl)cyclohexanecarbonitrile
  • 1-(2-Iodophenyl)cyclopropanecarbonitrile

1,2-Bis(diphenylphosphino)ethane (dppe)-ligated palladium(II) complexes catalyze the annulation of internal alkynes with 2-(cyanomethyl)phenylboronates to provide 3,4-disubstituted-2-naphthalenamines in good yields. The annulation reaction proceeds under mild and neutral conditions and requires methanol as an essential solvent. In addition to symmetrical alkynes, unsymmetrical
