The new complex Fp(η1-C5H4CH3) (2) was prepared and its fluxionality studied. Complex 2 was found to have a higher energy barrier for the fluxional process than the related systems Fp(η1-C5H5), η5-C5Me5Fe(CO)21-C5H5), and Fp(η1-C5H4CONHTs) (3). Reaction of 2 with dimethyl acetylenedicarboxylate gave a mixture of two cycloadducts where the methyl-group was found in the 5- and the 1-position in a ratio of 3 1, respectively. In both cycloadducts the Fp moiety was found regio- and stereoselectively in the 7-position and anti to the carboxylate groups. The molecular structure of crystalline 3 was determined and showed that the CONHTs substituent of the η1-ring was in the 1-position.
