represents one of the first examples of the addition of an organopalladium moiety to the carbon-nitrogentriplebond of a nitrile. The reaction is compatible with a number of functional groups. A reaction mechanism, as well as a model accounting for the electronic effects of substituents on the aromatic ring of the nitrile, is proposed.

A one‐pot universal approach for transforming arylamines to aryl halides via reaction with sodium nitrite (NaNO2) and N‐halosuccinimide (NXS) in DMF at room temperature under metal‐ and acid‐free condition is described. This new protocol that is complementary to the Sandmeyer reaction, is suggested to involve the in situ generation of nitryl halide induce nitrosylation of aryl amine to form the diazo

The sulfuric acid-promoted cascade cyclization of 2-(3-hydroxyprop-1-ynyl)benzonitriles led to an efficient synthesis of spiro[indene-1,1′-isoindolin]-3′-ones. This class of spiro compounds could also be prepared by the sulfuric acid-catalyzed cyclization of 2-(phenylacryloyl)benzonitriles, which were readily derived from 2-(3-hydroxyprop-1-ynyl)benzamides using trifluoroacetic acid as a catalyst.

palladium-catalyzed Ullmann cross-coupling of β-iodoenones and β-iodoacrylates such as 5 (X = I) with o-halonitroarenes and o-iodobenzonitriles including 2 affords products such as compound7. These can be engaged in a range of reductive cyclization reactions leading to heterocyclic frameworks such as 3,4-benzomorphan derivative 43.
