The bis(μ‐hydroxo)‐bridged dioxovanadium site in [γ‐1,2‐H 2 SiV 2 W 10 O 40 ] 4− catalyzes the epoxidation of alkenes in the presence of only one equivalent of H 2 O 2 with a high yield of epoxide, high efficiency of H 2 O 2 utilization, unusual regioselectivity, and unprecedented diastereoselectivity (see picture).
