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.
使用Fe(CO)5 -NaBH 4 -CH 3 COOH-胺-炔和Fe 3(CO)12-胺-炔试剂体系制备的炔-铁羰基配合物,在25°C下与过量的胺反应生成环状酰亚胺的产量中等至良好。此外,使用Fe(CO)5-吡啶-N-氧化物系统制备的不饱和羰基铁物质与炔烃反应,生成相应的酸酐。
