摘要
trans-Stilbene undergoes epoxidation with a two-fold excess of sodium periodate in the presence of 2 mol% ruthenium(II) 2-(phenylazo)pyridine complexes. Selectivities for epoxide are in the range 34-75%, depending on the structure of the complex. The byproduct, benzaldehyde, is derived from competing oxidative cleavage of the double bond.
