四-和六-氢-4，7-亚甲基茚-1-酮和类似的引达省二酮（VIII）-（X）通过标题反应或在八羰基二钴的存在下由乙炔、二氢茚衍生物和一氧化碳催化生成。该方法导致立体选择性的theexo系列和甲基或苯基衍生的适当的单取代乙炔的酮总是发现邻近羰基。1H n.m.r.光谱的产物进行了讨论，并使用铕位移试剂与自旋去耦示出允许明确区分异构体methanoindacenediones（VIII）和（IX）。
Tetra- and hexa-hydro-4,7-methanoinden-1-ones and the analogous indacenediones (VIII)–(X) are formed stoicheiometrically by the title reaction or catalytically from acetylenes, norbornene derivatives, and carbon monoxide in the presence of octacarbonyldicobalt. The process leads stereoselectively to ketones of theexo-series and methyl or phenyl groups derived from the appropriate monosubstituted acetylenes are always found adjacent to the carbonyl group. The 1H n.m.r. spectra of the products are discussed and the use of an europium shift reagent together with spin decoupling is shown to allow clear distinction of the isomeric methanoindacenediones (VIII) and (IX).
