Dicobalt Octacarbonyl-Catalyzed Tandem [2 + 2 + 1] and [2 + 2 + 2] Cycloaddition Reaction of Diynes with Two Phenylacetylenes under CO
摘要:
[GRAPHICS]Novel 5-5-6 tricyclic compounds containing cyclopentenone have been constructed by the dicobalt octacarbonyl catalyzed tandem [2 + 2 + 1] and [2 + 2 + 2] cycloaddition reaction between a diyne and two phenylacethylene under CO pressure.
