The reaction of subero-, azelao-, and sebaconitrile (4, n = 6, 7, and 8) with diisobutylaluminium hydride (to give 5) and subsequenly with methylenetriphenylphosphorane leads to the openc-hain bis-phosphoranes 8 a-c, which have been characterized by the Wittig reaction.The same reaction sequence applied to adiponitrile produces the cyclic bis-phosphorane 9a.The previously unknown hydrocarbon 1,3,9,11-cyclohexadecatetraene (12) has been prepared from 8a and adipoaldehyde.
