Abstract

The recent switch from copper to rhodium-based catalysts has produced major improvements in both intermolecular1 and intramolecular2 cycloaddition reactions of diazocarbonyl com- pounds with benzene. Not only are yields of cycloheptatrienes (from intermolecular reaction) and bicyclo[5.3 .O]decatrienes (from intramolecular reaction) significantly higher with rho- dium catalysts, but the reaction conditions are sufficiently mild to permit isolation of kinetic ...
