Reactivity of strongly bonded molecules was considered by Thiele [60], who introduced the concept of residual valence. This is tied in with Bayer s strain theory in the sense that a solution for the same question was sought. Whereas the stereochemistry of the cycloalkanes made Bayer s theory obsolete, the later introduction of resonance more or less confirmed Thiele s intuition.
