Introduction of Acetoxyl Group in Tropone and Azulene Nuclei Using Palladium(II) Acetate: Reactions of 2-Aminotropones and Azulenes with Palladium(II) Acetate.
2-Substituted tropones reacted with Fe2(CO)9 or with Fe(CO)5 under irradiation to give iron tricarbonyl complexes coordinated at unsubstituted diene moiety. 2-Bromotropone afforded another iron tricarbonyl complex coordinated at substituted diene as a minor product. 2-Methyl-, 2-phenyl-, and 2-tosyloxytropones yielded di-π-allyl type diiron hexacarbonyl complexes. Furthermore, 2-dialkylaminotropones
