A Nanosized Gly‐Decorated Praseodymium‐Stabilized Selenotungstate Cluster: Synthesis,Structure, and Oxidation Catalysis

A flexible one‐pot strategy with pyramidal Se^IV heteroatoms was employed for the assembly of the praseodymium‐containing gly‐decorated polyoxotungstate {Pr₃(H₂O)₁₀Se₂W₂₂O₇₆(gly)₂]}₂(Se₂W₇O₃₀H₂)]¹⁸⁻ ( 1 a ), which is constructed from one {Se₂W₇O₃₀H₂} unit and two identical {Pr₃(H₂O)₁₀Se₂W₂₂O₇₆(gly)₂]} units. Furthermore, the catalytic performance of Cs₂Na₄H₁₂{Pr₃(H₂O)₁₀Se₂W₂₂O₇₆(gly)₂]}₂(Se₂W₇O₃₀H₂)] ⋅ 25 H₂O ( 1 ) for alkene epoxidation with hydrogen peroxide was investigated under mild reaction conditions, and the experimental results suggested that compound 1 exhibits good catalytic performance for the epoxidation of cyclooctene.
