hexa-1,5-diyne

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Employing a Cadiot-Chodkiewicz-type reaction, 3-bromopropyne-1-ol was reacted with 1,5-hexadiyne to give two products, 2,4,8-nonatriyne-1-ol (I) and 2,4,8,10-dodecatetrayne-1,12-diol (II), which were separated by use of appropriate solvents. Oxidative coupling of (I) gave 2,4,8,10,14,16-octadecahexayne-1,18-diol (III).
