    Notes: Polyynes, 8. - Synthesis of Amino and Bisamino Derivatives of OctatetrayneThe (7,8,8-trichloro-7-octene-1,3,5-triynyl)amines 4a,b, formed by the reaction of the corresponding lithium 4-aminobutadiynides 3 with perchlorobutenyne 1, are dechlorinated by butyllithium to give the lithium 8-aminooctatetraynides 5a,b. The latter react with chloromethyldiphenylsilane or with cyclohexanone to give the silylated and hydroxyalkylated compounds 6a,b and 7b, respectively. The unsymmetrically substituted octatetraynediamines 9a,b are obtained by treatment of the lithium compounds 5 with cyanogen bromide and by treatment of the formed bromoacetylenes 8 with piperidine or morpholine.

    Description / Table of Contents: Polyynes, 6. - Synthesis of HexatriynaminesPerchlorobutenyne (1) reacts with the lithium aminoacetylides 2 by substitution of the chloro atom bonded at the acetylene moiety to give the hexendiynamines 3. These can be transformed by butyllithium into the lithium hexatriynides 4, which by hydrolysis, by silylation, or by reaction with ketones and tert-butyl isocyanate, respectively, and by successive hydrolysis furnish the hexatriynamines with a hydrogen atom (5a), with silyl groups (5b - e), with hydroxyalkyl groups (6a - e), or with a carboxamide moiety (6f) in the ω-position.
    Notes: Perchlorbutenin (1) reagiert mit den Lithium-aminoacetyliden 2 unter Substitution des am Acetylenteil gebundenen Chloratoms zu den Hexendiinaminen 3. Diese lassen sich mit Butyllithium in die Lithium-hexatriinide 4 umwandeln, die nach Hydrolyse bzw. Silylierung oder nach Einwirkung von Ketonen bzw. tert-Butylisocyanat mit anschließender Hydrolyse die Hexatriinamine mit einem Wasserstoffatom (5a), mit Silylgruppen (5b - e), mit Hydroxyalkylresten (6a - e) oder mit einer Carboxamidgruppe (6f) in der ω-Position bilden.
