If the carbon's bonding sites aren't fully saturated, the structure will sometimes have an itinerant double bond or two, depending on what substituents the ring has (if any). This phenomenon is ...

The most challenging cases are those in which the carbon-ring structures are "saturated," which means their carbons are connected only with single carbon-carbon bonds. Saturated carbon rings are ...

A team of researchers at IMDEA Nanociencia institute and Università Cattolica del Sacro Cuore has unveiled a new class of gas ...

Since all the known carcinogenic hydrocarbons possess the condensed carbon ring structure, it was decided, by analogy with œstrone, to see if it were possible to break down the condensed ring ...

The ability to attach fluorine atoms to the previously difficult-to-access “alpha carbon” — the carbon immediately next to the nitrogen in the ring structure — could lead to the ...

A research team at the University of Münster has synthesized three-dimensional ring structures, known as cage molecules, as stable alternatives to flat aromatic rings used in pharmaceuticals. The ...
