6(7) one must be responsible. The similar effect has been proposed for the rearrangements of 3-acetoxy-(1E,4Z)-dienes shown in eq (5): the rate of rearrangement involving (E)-allylic acetate moiety might be decelerated because of the π-σ* hyperconjugative electron withdrawing inductive effect of a TBSO-group attached to it (ref. 4(c)).
