Fe(CO)5 and a catalytic amount of sodiumborohydride react with cycloheptatrienes in protic solvents to yield the corresponding tricarbonyl(eta 4-1,3-diene)iron complexes in a one-pot procedure, which has been found to be particularly efficient for the synthesis of the useful tricarbonyl(cyclo-heptadiene)iron complex.

Tricarbonyl(6-hydroxy-2,4-cycloheptadien-1-one)iron derived from tricarbonyl(tropone)iron was easily oxidized to give tricarbonyl(2,4-cycloheptadiene-1,6-dione)iron. This procedure was also extended to tricarbonyl(2-substituted tropone)iron and exo(bicyclo[5.1.O]octa-3,5-dien-2-one)tricarbonyliron to yield tricarbonyl(2-substituted 2,4-cycloheptadiene-1,6-dione)iron and tricarbonyl(2,4-cyclooctadiene-1

The regioselectivity (1,2 vs. 1,4) in the nucleophilic addition of organolithium reagents to tropone(tricarbonyl)iron complexes has been studied and found to be correlated with the relative hardness of the nucleophile (HSAB principle). X-ray structures of several 1,2 and 1,4 adducts are reported.
