A copper conundrum has researchers reevaluating how some counterintuitive chemistry really works. Last year, Robert J. Phipps and Matthew J. Gaunt of the University of Cambridge generated excitement ...
THE hydrogen isotope exchange between an aromatic compound and aqueous acid without the intervention of heterogeneous catalysts can be regarded as an electrophilic aromatic substitution reaction 1. It ...
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 ...
