Recent advances in transition-metal-catalyzed synthesis of conjugated enynes

Conjugated enynes are of great importance in organic synthesis, biochemistry and materials sciences. The most commonly used synthetic methods include cross coupling reactions and dimerization reactions of alkynes. Despite many robust strategies being established, the improvement of reaction efficiency and development of novel transformations have still been actively pursued in the past decade. This review covers recent advances in transition-metal-catalyzed reactions in these fields.
