acyl substituent across an alkene, oxyacylation of alkenes, using rhodium catalyzed C–O bond activation of an 8-quinolinyl ester is described. Our unsuccessful attempts at intramolecular carboacylation of ketones via C–C bond activation ultimately informed our choice to pursue and develop the intramolecular oxyacylation of alkenes via quinoline-directed C–O bond activation. We provide a full account
The Claisen rearrangement of allyl phenyl ethers with exceptionally bulky, oxygenophilic methylaluminum bis(4-bromo-2,6-di-tert-butylphenoxide) (reagent A) is found to exhibit an unusual behavior not observable in the ordinary thermal and Lewis acid-induced rearrangement.

Molybdenum hexacarbonyl effectively catalyses a tandem Claisen rearrangement-cyclization reaction of allyl aryl ethers to give good yields of dihydrobenzofurans.
