摘要：

The title reaction, which was detected by a comparison of the DSC analysis of title compound 2 with that of the corresponding bicyclo[3.3.0]octa-1,3-dienyl complex 3, takes place at 200-degrees-C with various dienophiles (dimethyl fumarate, dimethyl maleate, diphenylethyne, N-methylmaleinimide). 3,4-Dimethylenecyclopentenyl complex 12 most likely is the key intermediate of the reaction.
