Science never ceases to amaze us. Recently, a team of chemists at the University of California, Riverside achieved what once seemed impossible: they stabilized an extremely reactive molecule known as a carbene in water. This remarkable feat not only confirms a decades-old theory about vitamin B1 but could also reshape how medicines, plastics, and fuels are made in the future.

Belief
For more than 60 years, the idea that vitamin B1 (thiamine) could form a carbene during its biological function was considered far-fetched. The problem? Carbenes are so unstable that they vanish instantly when exposed to water. Since our bodies are mostly water, testing this theory was deemed impossible. But Professor Vincent Lavallo’s team finally proved otherwise.
Carbene
So, what exactly is a carbene? It’s a rare and short-lived molecule where a carbon atom has only six valence electrons instead of the usual eight. This “electron shortage” makes it incredibly reactive, almost like an untamed spark waiting to jump. In water, carbenes normally disintegrate instantly.
Yet back in 1958, chemist Ronald Breslow suggested that vitamin B1 used a carbene in its natural role inside the body. For decades, this bold idea was shelved as untestable—until now.
Protection
How did Lavallo’s team manage to keep a carbene alive in water? They essentially gave it a “chemical suit.” By designing what they call molecular armor, the scientists protected the carbene from reacting with water molecules.
The result was astonishing: the carbene not only survived but stayed stable for months. Researchers could analyze it with advanced tools like nuclear magnetic resonance and X-ray crystallography—something once thought impossible.
Accident
The most surprising part is that the team wasn’t even aiming to confirm Breslow’s theory. They were pursuing other chemical reactions when they stumbled upon results that perfectly matched his proposal. In other words, they solved a 60-year-old mystery by accident.
Benefits
This discovery has huge potential applications. Carbenes are already used in making medicines, plastics, and fuels. However, traditional methods require expensive, toxic solvents that generate dangerous waste. By stabilizing carbenes in water, chemists can now perform reactions that are cheaper, safer, and far more environmentally friendly.
Imagine pharmaceutical companies producing drugs without polluting byproducts, or materials being manufactured without harsh chemicals. This could mark a turning point in sustainable chemistry.
Future
Beyond practical uses, this finding opens doors to a deeper knowing of life itself. Many biological molecules are just as short-lived as carbenes, and until now, they’ve remained invisible. With this technique, scientists can finally observe them directly, instead of just theorizing about their existence.
As Vincent Lavallo himself said, we may be entering a new era of biological chemistry—an era where fleeting molecular processes can finally be seen in real time. What once seemed like a wild guess in the 1950s has now become a groundbreaking reality.
