Abstract

The mixed metal cluster Cp*IrOs₃(μ-H) ₂(CO)₁₀ (1) reacted readily with a number of group 16 substrates under chemical activation with TMNO. It reacted with C ₆H₅SH to afford the novel cluster Cp*IrOs ₃(μ-H)₃(CO)₉(μ-SPh) (2). It also reacted readily with Ph₃PSe to afford five new clusters, viz., Cp*IrOs₃(μ-H)₂(CO)₉(μ₃- Se) (3) Os₃(μ-H)₂(CO)₇(μ₃-Se) (PPh₃)₂ (4), Cp*IrOs₃(μ-H) ₂(CO)₉(PPh₃) (5), Cp*IrOs ₃(μ-H)₂(μ₃-Se)(CO)₈(PPh ₃) (6) and Cp*IrOs₃(μ-H) ₂(μ₃-Se)₂(CO)₇(PPh₃) (7). The reaction pathway for this reaction has been studied carefully and suggests that Ph₃PSe functioned primarily as a selenium atom transfer agent to give initially the even more reactive 3. The reaction of 1 with di-p-tolyl ditelluride yielded three new clusters, 8-10, which were non-interconverting stereoisomers with the formulation Cp*IrOs ₃(μ-H)₂(μ-Te-p-C₆H₄CH ₃)₂(CO)₈.
