Our country's scientists have made a new breakthrough in the preparation of alkynes from olefins.

Alkenes and alkynes are important cornerstones of modern synthetic chemistry, with significant research and application value. Chinese scientists have used a reagent with special activity to overcome the international challenge of preparing alkynes from alkenes that has persisted for over a hundred years, laying the foundation for the rapid acquisition of structurally diverse alkynes and the development of new drugs. This achievement was published online in the prestigious international journal "Nature" on the 17th.
