Hydride abstraction of tricarbonyl[η 4 ‐1‐(phenylsulfonyl)‐1,3‐cyclohexadiene]iron(0) complex 2 with Ph 3 C + PF 6 − 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.
