Cycloheptene is readily converted to the cationic cycloheptadiene-Mo(C0)2Cp complex, which reacts with a range of nucleophiles; hydride abstraction from the product π-allyl-Mo(C0)2Cp complexes give substituted cycloheptadiene complexes which react with a second nucleophile stereospecifically, and decomplexation of the π-allyl complexes gives substituted cycloheptene derivatives with defined relative

Catalysis of the Claisenorthoesterrearrangement of triethyl orthoacetate and a number of 2-cycloalken-1-ols has been achieved using acidic catalysis and brief microwavethermolysis in DMF. Unlike conventional methods of thermolysis, very high yields of rearranged products are typically obtained in less than ten minutes, and the Claisen products themselves require no further purification. The synthetic
