The effect of substituents on the rearrangement of allyl aryl ethers has been investigated extensi~ ely.~-7 These studies have led to a definition of the stereochemical'and electrical6 nature of the transition state of this rearrangement. However, the isomerization of allyl mX- phenyl ethers has not been systematically examined, and the scanty information which is n~ ailable5 indicates thesc compounds may behave soniewhat anomalously. Therefore, it ...
