Bis(benzotriazol-l-yl) methylimine was used as a novel electrophilic cyanating agent for labile β-diketonates (M = CuII, NiII, CoII, ZnII and CdII). The actual cyanating species was 1 -cyanobenzotriazole formed in situ with the elimination of benzotriazole. The labile metal-oxygen bond in the chelates possibly induced debenzotriazolation. The inert and less labile β-diketonates did not undergo this reaction. The final product of the reaction, however, was the mixed-ligand complex of cyano-β-diketone and benzotriazole, identified by spectral and analytical methods. Copyright © 1996 Elsevier Science Ltd
