Recent research challenges the long-held belief that high-energy carbon species, like carbenes, cannot survive in water. A study shows that such reactive carbon species can last in water long enough to be observed, offering new insights into how some enzymes function in cells and potentially improving industrial chemistry by allowing reactions to occur in this safe, inexpensive solvent.
Historically, the idea that vitamin B1 (thiamine) could create carbene-like species in cells emerged in 1958 but was met with skepticism, as carbenes were thought to disintegrate instantly in water. New experimental techniques led to the creation of a protective molecule that allows carbenes to persist in water, confirmed through nuclear magnetic resonance (NMR) spectroscopy and X-ray crystallography.
This breakthrough opens doors for safer chemical manufacturing since many processes currently rely on hazardous organic solvents. It demonstrates that carbenes can indeed operate in water, reinforcing past theories about vitamin B1’s role in metabolic reactions. The researchers underscore the importance of evolving methodologies in science, which allow for the confirmation of bold ideas initially deemed implausible. The findings highlight a potential shift towards more environmentally friendly chemistry while paving the way for discovering other short-lived reactive species.
The complete study was published in “Science Advances.”
