Dicobalt octacarbonyl is shown to react with acetylene and carbon monoxide under mild conditions in dimethoxyethane or benzene to produce, in low yields, bicyclo[3.3.0]octa-3,7-diene-2,6-dione, benzoquinone, and the cyclopentadienone-derived products 3a,4,7,7a-tetrahydro-2,7-methanoindene-1,10-dione, 1-indanone, tetracyclo[5.5.2.02,608,12]tetradeca-4,10,13-triene-3,9-dione, and tetracyclo[5.5.2.02
已显示八羰基二钴在温和的条件下在二甲氧基乙烷或苯中与乙炔和一氧化碳反应,以低收率生产双环[3.3.0]八-3,7-二烯-2,6-二酮,苯醌和环戊二烯酮衍生产品3a,4,7,7a-四氢-2,7-亚甲基茚-1,10-二酮,1-茚满,四环[5.5.2.0 2,6 0 8,12 ] tetradeca-4,10,13-三烯-3,9-二酮和四环[5.5.2.0 2,6 0 8,12 ]十四碳-4,9,13-三烯-3,11-二酮。讨论了形成这些产物的可能机制。
