lkyl-3,5-diacetylenes with powdered NaOH was used for the synthesis of terminal 1-alkyl-1,3-butadiynes that can be isolated (54–97%) or used in situ. In an attempt to increase the yields of some of the obtained products, different experimental conditions were studied and we found that by using CTAB as a catalyst, a prototropicrearrangement was promoted to afford the 1-methyl-4-alkyl-1,3-diacetylenes

A three-stage method was developed for the synthesis of diacetylene azides from diacetylene alcohols prepared by Cadiot-Chodkiewicz reaction. By their bromination the corresponding diacetylene bromides were obtained whose azidation resulted in the target diacetylene azides. The attempt was performed to prepare azides of triacetylene series, but the low stability of the synthesized triacetylene alcohols prevented their conversion into the corresponding bromides.
