Bismuth(III) triflate catalyzed Claisen and Fries rearrangements of allyl phenyl ethers and phenyl acetates have been presented. The reaction proceeds smoothly and yields corresponding rearranged products in good yields. The bismuth triflate displays higher activity over the corresponding La, Yb, and Sc triflates.

Substituted-2-hydroxy-3-allylacetophenones 2 react with cinnamoyl chlorides 3 in potassium carbonate-acetone to give good yields of polyfunctional 1-(2-hydroxy-3-allylaryl)-5-aryl-4-pentene-1,3-diones 4 which exist in their enol forms 5. These on acid cat
