The [2 + 1] cycloaddition reaction of electron-rich alkenes such as enol ethers with 9-diazo-9H-fluorene (1) is efficiently catalyzed by pentacarbonyl(Ξ· 2 -cis-cyclooctene)chromium(0) (2). This cyclopropanation reaction shows a pronounced preference for electron-rich C=C bonds, as demonstrated by th
