A catalytic version of the intramolecular Ni-promoted tandem cyclization-cyanation process is described. Generally, the reaction leads to mixtures of cyclic and open chain adducts in moderate to good yields. The presence of external bidendate nitrogen ligands, although not essential for the reaction outcome, provides stability to the catalytic system. (C) 1999 Elsevier Science Ltd. All rights reserved.
