Thermolysis with either Mo(CO)6 or Mo(CH3CN)3(CO)3 of 2,3-dicarbomethoxy-7-oxabicyclo<2.2.1>heptadiene (I) gave three major products, i.e. dimethyl phthalate (V), 3,4-dicarbomethoxyfuran (VI), and a dimeric ketone (IX) linked in an exo-trans-exo orientation.The formation of V and IX indicates two reaction pathways which start from a common organometallic intermediate.Compound VI is the major product in the thermal decomposition of IX.
