The 1-dimethoxymethyl-5,6-dimethylidene-7-oxabicyclo<2.2.1>hept-2-ene (9) has been prepared.On treatment with Fe2(CO)9, the endocyclic double bond C(2)=C(3) was coordinated first giving the corresponding exo-Fe(CO)4 complex 10.The latter reacted with Fe2(CO)9 and afforded cis heptacarbonyl-μ-<1RS,2SR,3RS,4SR,5RS,6SR)-2,3-η-(1-(dimethyoxymethyl)-5,6-dimethylidene-7-oxabicyclo<2.2.1>hept-2-ene)>diiron (11) as a major product.On heating, 11 undervent deoxygenation of the 7-oxabicyclo<2.2.1>heptene moiety yielding tricarbonyl
