A team of chemists has achieved the unprecedented: stabilizing a notoriously reactive carbene molecule in water, validating a decades-old theory about vitamin B1 and offering a greener path for chemical manufacturing. Chemists have successfully generated an unstable molecule in water, a feat once believed to be impossible. Chemists have confirmed a 67-year-old theory about vitamin B1 by stabilizing a highly reactive molecule in water, a breakthrough that was long considered impossible. This discovery not only resolves a long-standing biochemical question but also paves the way for more sustainable and efficient methods of producing pharmaceuticals. The molecule involved is a carbene,...
