Carbon-carbon double bonds, also referred to as alkenes or olefins, are present in many medicinally relevant and biologically active molecules.
Molecules with carbon–carbon double bonds are known as "olefins." Typically, the carbon atoms in these bonds, and the atoms attached to them, lie in the same geometric plane.
Chemistry recognizes triple bonds between all possible combinations of the four elements—but not between boron and carbon.
Still, one bond – a triple bond between boron and carbon – remained elusive, despite the existence of stable double bonds and ...
Most catalytic methods have been developed to target the more reactive carbon–carbon double bonds in alkenes. A catalytic system that can selectively work on the less reactive carbon-hydrogen bond ...
Now chemists have expanded the library of such molecules, creating a trio of transuranium complexes that contain double bonds between neptunium and carbon (J. Am. Chem. Soc. 2022, DOI: 10.1021 ...
While a double bond is stronger than a single bond, it is less stable, making it easier to cleave. They, like Scott’s team, sequentially removed hydrogen from smaller and smaller carbon chains ...
In the first step of the reaction, the double bond is converted into an epoxide, a three-membered ring with one oxygen and two carbon atoms. The epoxide is able to react with CO 2 in the presence ...
Carbon bond that uses only one electron seen for first time: ... In particularly strong bonds, atoms might share two electron pairs in a double bond, or three pairs — a triple bond.
Chemist Prof. Dr. Bernd F. Straub and his team are the first to have created the basis for directly examining the otherwise unstable gold-carbon double bond. Prof. Straub explains that highly ...
Most polymers have at least one carbon-carbon double bond, which is much easier to break. While isomerizing ethenolysis had been tried by the same researchers before, ...
