摘要：

Tricarbonyl(eta(6)-1,2-dioxobenzocyclobutene)chromium(0) 1 can be converted into benzocyclooctenedione derivatives 3, 7 and 8 as well as fused five-membered ring systems 2, 4 and 6 by addition of vinyl lithium derivatives and following double anionic oxy-Cope rearrangement under very mild reaction conditions (-78 degrees C); product ratios depend on the method of hydrolysis.
