Perchlorobutenyne (1) reacts with the lithium aminoacetylides 2 by substitution of the chloro atom bonded at the acetylene moiety to give the hexenediynamines 3.These can be transformed by buthyllithium 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.
