CODEN: GWXXBX.Several substances like 90-02-8 may be metioned in this study. CLASS: IC: C09B055-00. APPLICATION: DE 76-2611697 17 Mar 1976. DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Azomethine complexes I[Z = C(CN):C(CN), 5,6-dicyano-2,3-pyrazinediyl; M = Ni, Cu], their corresponding sym. benzo derivs., unsym. derivs., and polymeric derivs. were prepd. by a variety of methods. For example, salicylaldehyde [90-02-8] was dissolved in EtOH, a catalytic amt. of H2SO4 added, diaminomaleonitrile [1187-42-4] added, the mixt. heated, the Schiff base [56029-20-0] isolated, and treated with 5-bromosalicylaldehyde [1761-61-1] and Ni acetate to give II [64659-52-5]. ..
