Researchers at Peking University have achieved a monumental breakthrough in synthetic chemistry, solving a problem first posed in 1861. The team, led by Professor Jiao Ning, has developed a method to efficiently transform olefins—cheap derivatives of coal—into high-value alkynes, which are essential building blocks for the pharmaceutical industry.
The study, published in the journal Nature on March 16, 2026, addresses a 160-year-old challenge of converting “double-bonded” carbon chains (alkenes) into “triple-bonded” ones (alkynes) under mild and scalable conditions.
The Breakthrough: From “Olefins to Alkynes”
While China already possesses mature Coal-to-Olefins (CTO) technology, most of the resulting material is used to create inexpensive plastics. This new “shortcut” allows the industry to move up the value chain toward life-saving drugs.
- The “Magic” Reagent: The team revived a long-forgotten chemical called selenanthrene. First synthesized in 1896 but ignored for over 130 years, it acts as a recyclable mediator that allows the conversion to happen at room temperature.
- Molecular Surgery: The process functions like “molecular surgery,” precisely stripping hydrogen atoms to create the triple bonds necessary for complex drug frameworks.
- Mild Conditions: Previous methods required extremely harsh chemicals or high heat, making them impossible to use for delicate medicinal compounds. This new method is both green and highly efficient.
Why It Matters: “Coal into Gold”
This discovery is being hailed as a strategic win for China’s energy and pharmaceutical security, especially as global oil supplies remain volatile due to the West Asian conflict.
1. High-Value Pharmaceuticals
Alkynes are the structural “skeletons” for many critical medicines, including:
- Antiviral Drugs: Essential for treating HIV and hepatitis.
- Anticancer Agents: Used in targeted therapies to stop cell growth.
- Antibiotics: Providing a new route to synthesize next-generation bacterial fighters.
2. Economic Transformation
China currently operates over 36 CTO projects with a capacity of 24 million tonnes. By turning just a fraction of this output into medicinal precursors, the value of the raw material increases exponentially.
“This is the core technology that helps China truly ‘turn coal into gold,'” noted one industry expert in Beijing. “We can now create immense value without needing more oil.”
Comparison: The Old Way vs. The Jiao Method
The leap in efficiency is significant for industrial-scale production.
| Feature | Traditional Synthesis | Jiao Ning’s Breakthrough |
| Raw Material | Expensive Oil-based precursors | Cheap Coal-based Olefins |
| Temperature | High heat / Harsh catalysts | Mild / Room Temperature |
| Scalability | Limited by cost and safety | High (uses recyclable reagents) |
| Environmental Impact | High waste / Toxic byproducts | Green / Sustainable |
Future Outlook: The “Agentic” Factory
In a separate but related development, Xiaomi and Baidu have hinted that their new MiMo-V2 and OpenClaw AI agents are already being trained on this new chemical data. The goal is to create autonomous chemical labs that can use Professor Jiao’s method to “print” specific drug molecules on demand by 2028.
