involving the activation of an allenic C(sp2)H over an allylic C(sp3)Hbond is described. In this ene reaction, the presence of a silyl substituent was found to be critical for the observed reactivity and selectivity since the corresponding alkyl‐substituted allenes show different reaction profiles. Computational studies show that the origin of this unusualreactivity is the lower bond dissociation
