The equilibria 2x 3e and 9x 11 of the title compounds reveal a slight influence of methoxy substituents on the stability of cyclopropane rings.Reactions which involve the distal cyclopropane bond - the butadienylcyclopropane rearrangement of 2 and the homo-1,5-H shift of 9 - are but modestly accelerated by methoxy groups.The vinylcyclopropane rearrangement 9x -> 10 confirms the strong methoxy effect on proximal cyclopropane bonds.
