Gold-catalyzed Reactions of Substituted 1,5-diynes: Recent Advances and their Chemistry

Diynes are identified as exceptionally potent and superior substrates in gold-catalyzed organic transformations. Gold (I) and gold (III) complexes exhibit unique activity towards diynes, encouraging the nucleophilic addition of different functional groups both inter and intra- molecularly. In this review, particularly, we focused on recent advances in gold-catalyzed reactions of 1,5-diynes along with their mechanistic aspects. These reactions are interesting for constructing molecular complexity, medicinal chemistry, and material science.
