Single–carbon atom transfer to α,β-unsaturated amides from N-heterocyclic carbenes. Science , 2023; 379 (6631): 484 DOI: 10.1126/science.ade5110 Cite This Page : ...

The research, recently published in the journal Nature under the title "One-carbon homologation of alkenes," unveils a breakthrough method for extending molecular chains—one carbon atom at a ...

A new reagent has moved carbon-atom transfer out of the chemical flatlands, allowing chemists to place a single carbon atom so that it makes bonds to four different substituents. The reagent makes ...

Last year, Li and her colleague Quang Luu, also at Iowa State University, unveiled a reaction sequence that replaces a carbon atom with oxygen, a change that can potentially improve a molecule’s ...

Each water molecule is made from two hydrogen atoms chemically bonded to one oxygen atom. This means that the chemical formula of water is H₂O. Carbon dioxide is made of molecules of a carbon ...

Researchers from Osaka University have used single carbon atom doping to form four chemical bonds in one step. Gamma-lactams (cyclic molecules that are common in antibiotics) were easily ...

Published in the Journal of the American Chemical Society, the study introduces a safe, sustainable technique for adding a single carbon atom to drug molecules at room temperature.

These chemical operations can all be done in one pot. The upshot is that a wide variety of quinolines can be converted to quinazolines in typical yields of about 50–90%.

Chemically, carbon dioxide is incredibly simple – it is just one carbon atom linked with two oxygen atoms. Together they create a colorless gas that makes up just a tiny fraction of the Earth's ...

Each line represents a pair of shared electrons, forming double bonds between the carbon and each oxygen atom. Molecular Geometry of CO 2. The molecular geometry of CO 2 is linear.
