The sonochemical arylation of active methylene compounds

The sonochemical arylation of active methylene compounds with haloarenes have been studied. The reaction course was found to be dependent on the electron-withdrawing properties of substituent and the leaving group of haloarenes as well as of the character of active methylene compounds. The results of the sonochemical experiments were just slightly better than in the classical onesʹs, exception being reactions with phenylsulfonylacetonitrile.
