A ring-shaped molecule may possess a cavity because of its three-dimensional structure. This cavity can accommodate a guest molecule if its size (configuration) is adequate for the cavity, while it ...
A leading synthetic challenge for chemists is how to precisely target a single C–H bond for reaction among many similar-looking ones in an organic molecule. Carefully crafted transition-metal ...
PAUL VON RAGUÉ SCHLEYER says the idea hit him while teaching a graduate class on the structure and energy of organic molecules: The mechanism that irrefutably stabilizes branched alkanes should ...
