Abstract

[{Cp ^*Rh(S ²C ₆H ₄)} ₂W(CO) ₂] (Cp ^*: η ⁵-C ₅Me ₅) (1) and [{Cp ^*Rh(S ₂C ₆H ₄)}(S ₂C ₆H ₄)W(CO) ₂] (2) were synthesized by the reaction of rhodadithiolene [Cp ^*Rh(S ₂C ₆H ₄)] with [W(CO) ₃(py) ₃], and their crystal structures and physical properties were investigated. The formation mechanism of 2 from 1 was pursued by ¹H NMR spectroscopy. 1 reacted with an excess amount of BF ₃·Et ₂O to furnish 2, indicating that a Lewis acid assisted the demetalation reaction.
