โฆ Synopsis
Cycloheptene is readily converted to the cationic cycloheptadiene-Mo(CO)2CP complex, which reacts with a range of nucleophiles; hydride abstraction from the product 7allyl-Mo(CO)2C p complexes give substituted cyeloheptadiene complexes which react with a second nueleophile stereospeeifically, and decomplexation of the ~-allyl complexes gives substituted cycloheptene derivatives with defined relative stereochemistry.
