    • We use the term "C-H bond nucleophilicity" when referring to the "electronic reactivity factor". It seems to us that this term pragmatically denotes the effect of what hyperconjugative and inductive electronic effects might transmit from neighboring substituents to the reaction site. Thus, this term can refer to both activation as well as deactivation of the C-H bond by neighboring substituents towards electrophilic "C-H activation" insertion reactions

In 1955, strain release was put forward as a reactivity factor to explain the differing reactivity of axial and equitorial alcohols during oxidation. The same rationale may account for the differing rates of activation between axial and equitorial C-H bonds in C-H activation processes (see scheme)
