Used in combination with a Pd(0) catalyst in improved procedures for the cyanation of aromatic halides, instead of the classical Rosenmund-Von Braun (CuCN) method: Synth. Commun., 24, 557 (1994); Tetrahedron Lett., 40, 8193 (1999); 41, 3271 (2000); 45, 1441 (2004). For cyanation of aryl triflates, see: Tetrahedron Lett., 39, 2907 (1998); Synlett, 1207 (1998).
