Stereochemical Impacts on Acyclic Mechanochemical Carbon-Carbon Bond Activation.

As a consequence, in cyclic mechanophores the transition states are quite different from each other, while in BP, free rotation leads to similar transition state structures where the only differences are a consequence of the stereochemistry—and, as we show here, this effect can be quite significant, particularly if the substituents interact differently when syn and anti to each other.
