| Abstract: | Alkyne-iron carbonyl complexes, prepared using Fe(CO)5-NaBH4-CH3COOH-amine-alkyne and Fe3(CO)12-amine-alkyne reagent systems, react with excess of amine at 25 °C to give cyclic imides in moderate to good yields. Further, unsaturated iron carbonyl species, prepared using the Fe(CO)5-pyridine-N-oxide system, react with alkynes to give the corresponding anhydrides. |
