Abstract
Tetracyanoethylene, hexafluoroacetone, 1,1-dicyano-2,2-bis(trifluoromethyl)ethylene, and 1,2-dicyano-1,2-bis-(trifluoromethyl)ethylene add exo-1,3- to tricarbonylcycloheptatrieneiron; the Fe(CO)3 group is bonded in the 1,2,3,5-h4 mode in the resultant adducts. A similar reaction occurs with tetracyanoethylene and tricarbonyl-(methyl-, bromo-, and phenyl-cyclo-octatetraene)iron. The cycloheptatriene iron adducts undergo an unusual transannular carbonylation reaction.Keywords
