Abstract
The reaction of o-acyloxybenzylidenetriphenylphosphoranes with substituted benzoyl chlorides in an aprotic solvent led, together with the expected 2-phenylbenzofuran, to isomeric 3-benzoyl-2-phenylbenzofuran derivatives. This result formally corresponds to intramolecular migration of the benzoyl group from the ortho oxygen atom to the ylide carbanion via cyclization and ring opening of the starting o-acyloxybenzylidenetriphenylphosphoranes.File | Dimensione | Formato | |
