The title compound 3 reacted with soft nucleophiles to give η4-complex 4 as the only product, but in the case of hard nucleophiles, the σ,η3-complex 5 was also obtained. Synthetic applications of the addition products were also studied.

Hydride abstraction of tricarbonyl[η4-1-(phenylsultonyl)-1,3-cyclohexadiene]iron(0) complex 2 with Ph3C+PF6-, regiospecifically provided the title compound 3 in excellent yield. Cationic complex 3 could react with a variety of nucleophiles in good yields. Soft nucleophiles prefer to attack at the C-5 position, whereas hard nucleophiles such as methyllithium and the enolate of ethyl acetate gave the C-5 as well as the C-2 addition products. Some synthetic applications of the addition products were also studied.
