The (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.
