Abstract

The reaction of the cluster Os ₃(CO) ₁₀(μ-H)(μ- γ-C ₅H ₃O ₂) (1), with DMAD under UV irradiation afforded three isomers of the monosubstituted product, Os ₃(CO) ₉(μ-γ-C ₅H ₃O ₂)(μ ₃-MeO ₂CCHCCO ₂Me) (2), and a disubstituted product, Os ₃(CO) ₈(μ-γ-C ₅H ₃O ₂)(μ ₃-MeO ₂CCHCCO ₂Me)(μ-MeO ₂CCCCO ₂Me) (3). The formation of 3 suggests that flipping of the O-heterocycle can occur.
