Abstract
The chromium carbene Dotz annulation reaction proceeds very rapidly in the presence of ultrasound giving good yields of quinone product on o xidative workup. Moreover, the yield of annulated product has been imp roved by adsorbing the reagents onto silica and heating at moderate te mperatures. Both these modifications have proved to be successful for a variety of complexes and alkynes.
