When either enantiomer of exo-2-norbornyl bromide reacts with a nucleophile, a racemic mixture of products results. Explaining the stereochemical outcome of this reaction has been at the heart of a ...

For organic chemists, the free-radical hydrostannylation of alkynes to produce vinylstannanes is a key step in important cross-coupling and other reactions. Every published mechanism has hinged solely ...
