                                    The title reaction gives, depending on conditions, either substituted tetraenic omega-dimethylaminodinitrile or a substituted 1,1,3,11,13,13-hexacyanotrideca-1,3,5,7,9,11-hexaenide salt; a series of new cation-anionic polymethyne dyes have been obtained from the latter.
