Iron carbonyl species, prepared in situ in THF using Fe3(CO)12, react with alkynes at 25°C, in the presence of certain amines, to give the corresponding cyclobutenediones in moderate to good yields (25–61%) after CuCl2·2H2O oxidation.
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.

Succinimide derivatives are useful building blocks for the synthesis of natural products and drugs. We describe an efficient route to succinimide derivatives comprising Pd(xantphos)Cl2-catalyzed aminocarbonylation of alkynes with aromatic or aliphatic amines in the presence of p-TsOH. The utility of this route is demonstrated with the synthesis of a large number of succinimide compounds including an important photochromic molecule.
