Rhodium( II )‐catalyzed reactions of diazodicarbonyl compounds with a variety of conjugated dienes have been examined. These reactions provide a simple and rapid route to dihydrofurans and dihydrooxepines with a variety of substituents on the ring. The formation of these products is interpreted in terms of a stepwise mechanism. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
