Thiuram Disulfide Mediated Cu-Catalyzed Amidation of Terminal Alkynes: An Efficient Synthesis of Alkynyl Amides
Sourav Mondal, Soumya Mondal, Amit Saha
Abstract
Terminal alkynes undergo a CO-free aminocarbonylation reaction mediated by thiuram disulfides. Thiuram disulfide acts as the source of the carbamoyl group in the amidation of terminal alkynes in the presence of copper-based reagent and catalyst. A series of alkynyl amides has been prepared with several structural variations following the current one-pot two-step protocol. The reaction proceeds through a mixed disulfide intermediate, which has been isolated and characterized by single-crystal XRD analysis.
