Diyne

Diynes are organic compounds that have two triple bonds. The name is derived from di for two and the suffix - in in alkynes, the main class of organic compounds with triple bonds, from.

Production

Symmetrical conjugated diynes can be obtained by Glaser coupling, unsymmetrical diynes by a Cadiot - Chodkiewicz coupling. Here, a terminal alkyne and a bromoalkyne be catalyzed by copper salts in cross-coupling linked.
