| Abstract: | Reaction of the title compound with ArLi (Ar = Ph; o-, m-, p-tolyl; p-MeOC6H4; p-ClC6H4) in ether at low temps., and subsequent alkylation of the formed acylmetalates with Et3OBF4 in aqueous solution at 0?led to the novel ring-opening reaction of the bicyclodiene ligand to give the chelated diallyl dicarbonyliron complexes of composition (C12H6F4)(CO)2FeC(OC2H5)Ar. The structure of one complex was determine by x-ray crystallog. |
