| Abstract: | The reaction of 2,3,5,6-tetrakis(methylene)-7-oxabicyclo2.2.1]heptane (I) with iron carbonyls in various solvents yields the (η4-1,3-diene)Fe(CO)3 isomers (II: exo; III: endo) and the bimetallic isomers bis(η4-1,3-diene)Fe(CO)3] (IV: bis(exo); V: endo,exo). In weakly coordinating solvents, a parallel rearrangement of I occurs through CO bond cleavage of the allylic ether by Fe2(CO)9 yielding an unsaturated ketone (VI) bonded to two Fe(CO)3 groups through a trimethylenemethane and a 1,3-diene system, respectively. The geometries of III and VI have been ascertained by X-ray crystal structure determinations. |
