Abstract
Abstract In position 3 (and 5) substituted phenyl-γ-methyl (and phenyl)-allylethers when subjected to the thermal C LAISEN-rearrangement not only yield the expected o-allyl- phenols but in addition considerable amounts of the P-allylated phenols. Migration to the para-position is favoured by non-polar solvents. This para-migration of the substituted allylgroup is attributed mainly to steric factors. With sterically hindered, in ortho-or para- ...
