The syntheses and characterization of the tricarbonylchromium complexes of 1,3-indandione and ninhydrin are described. As the direct complexation proved unsuccessful, the acetal route was tried. Although some complexes were obtained, complex deacetalization did not work in the case of ninhydrin. Finally, the oxidation of tricarbonyl(η6-1,3-indandione)chromium(0) with dimethyldioxirane gave the ninhydrin
描述了 1,3-茚二酮和茚三酮的三羰基铬配合物的合成和表征。由于直接络合证明不成功,因此尝试了缩醛路线。虽然得到了一些配合物,但在茚三酮的情况下,配合物脱缩醛不起作用。最后,三羰基(η6-1,3-茚二酮)铬(0)与二甲基二环氧乙烷的氧化得到茚三酮配合物,与茚三酮配合物平衡时产率为75%。后者在杂 Diels-Alder 反应中与二烯反应,非对映选择性地形成螺烷化的吡喃衍生物。
