Using computer simulations, researchers showed the crystal p - tert - butylcalix [4] arene easily pulls in carbon dioxide. (pnnl.gov)
Moreover, the reaction is broadly tolerant of groups such as halogens, esters, and nitriles, and it manifests complementary site - selectivity to arene C - H borylation reactions. (science.sciencemag.org)
The study, published online on January 26, 2015 in Nature Chemistry, reveals the first example of the controlled synthesis of benzene with different arene groups at all six positions «at - will», demonstrating the potential of this method to synthesize useful aromatic materials in a predictable and programmed manner.
