A cyclobutadiene equivalent in the catalytic Pauson-Khand reaction

A practical and scalable operation: The reaction shown in the scheme, which uses catalytic amounts of hexacarbonyldicobalt, gives access to versatile bicyclic systems, which until now could only be obtained in low quantities by a photochemical process starting from tropolones. An isolation of the primary Pauson-Khand products is not necessary.

High-Pressure Diels-Alder Reaction of Cyclooctatetraene with Dimethyl 1,4-Dimethyl-7-oxabicyclohepta-2,5-diene-2,3-dicarboxylate. Single Crystalline State Valence Isomerization of a syn-Tricyclo2,5>octane Derivative

High-pressure Diels-Alder reaction of cyclooctatetraene with dimethyl 1,4-dimethyl-7-oxabicyclo-hepta-2,5-diene-2,3-dicarboxylate afforded six products, one of which was shown to be a 2:2-adduct having a syn-tricyclo2,5>octane framework.Upon radiation with X-rays, the tricyclooctane derivative isomerized to a cyclooctadiene derivative.
