Revolutionary Reaction Solves 160-Year-Old Chemistry Challenge

Solving a Problem from the 1860s

Published in the Nature journal in March 2026, this groundbreaking research was led by a team from Peking University (Beijing, China) under the guidance of Professor Ning Jiao.

A longstanding challenge in organic chemistry has been the conversion of alkenes into alkynes.

The problem was:

  • Converting alkynes to alkenes has long been routine,
  • but the alkene to alkyne transformation required:
    • strong bases,
    • high temperatures,
    • and was incompatible with functional groups.

This made it nearly unsuitable for industrial and pharmaceutical applications. According to the Nature article, this classic method has operated on the same principle since the 1860s.

The Breakthrough: "Molecular Editing" with a New Catalyst

The Chinese research team developed a new system featuring a:

  • reversible catalytic "carrier"
  • capable of:
    • removing hydrogens from alkenes
    • to directly create alkynes

Instead of a forceful elimination, it involves gentle, stepwise dehydrogenation. The results published in Nature suggest this is not just a new reaction but a new approach to targeted molecular editing in organic chemistry. This means chemists are not merely "synthesizing" but rewriting existing structures at the molecular level.
