Few roads lead to meta, much to the chagrin of organic chemists trying to build compounds of particular shapes. Now researchers have found a simple way of getting molecules into the coveted meta ...

Arginine (Arg, R): Arginine has a guanidinium group as its R group, a complex nitrogen-containing group that is positively ...

The term aromaticity is a basic, long-standing concept in chemistry that is well established for ring-shaped carbon compounds. Aromatic rings consisting solely of metal atoms were, however, heretofore ...

A research team at the University of Münster led by chemist Prof Frank Glorius has synthesized so-called heteroatom-substituted cage-like 3D molecules. The innovative structures could help address key ...

Chemists have yet another use for fluorine, as a through-space activator for electrophilic aromatic substitutions. Thomas Lectka and coworkers at Johns Hopkins University used a Diels-Alder reaction ...
