Treatment of β-arylpropionitriles with aryllithiums, followed by the reaction with water and then with NIS under irradiation with a tungsten lamp gave 2-arylquinolines in good to moderate yields. The present reaction proceeds through the formation of N-iodoimines from imines with NIS, the generation of imino-nitrogen-centered radicals, and their cyclization onto the aromatic rings of the imines to

An efficient procedure for the synthesis of 2,2-disubstituted benzocyclic ketones by intramolecular carbopalladation of nitriles has been developed. The cyclization of substituted 3-(2-iodoaryl)propanenitriles affords indanones in high yields. The reaction is compatible with a wide variety of functional groups. This chemistry has been extended to the synthesis of tetralones, a 9-fluorenone and a cyclopentenone
