Controlling Factors Determining the Regiochemistry of Intramolecular Alkoxymercuration.
-The regioselectivity of intramolecular alkoxymercuration of compounds ( I) is closely related to the Hammett constants of the substituents on the benzene ring and is further effected by the solvent leading to the corresponding benzyltetrahydrofurans and/or phenyltetrahydropyrans (as sole product in case of (Ic)). -(SENDA, Y.; KANTO, H.;
