Stereochemical consequences of dynamic gearing in substituted bis(9-triptycyl) methanes and related molecules
Empirical force-field calculations show that bis(9-triptycyl)methane has a C(s) ground state and that the securely meshed triptycyl groups undergo nearly unhindered cogwheel rotation through a C(2) transition state, with an activation energy of ≈1.0 kcal mol(-1). These features lead to note-worthy s...
