摘要：

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