Conjugated Diyne Chemistry: Synthesis, Natural Existence and Applications

1, 3-butadiynes, also known as the conjugated diynes, are important structures with rigid full-carbon sketch, and they have been found to exist widely in nature from the marine organisms to the interstellar space. Besides the special physiological activities, diynes have also been found to be crucial in material science. This review will focus on the synthesis of diynes, and more importantly, their existence and bioactivities, as well as their applications and further developing trends.
