✦ Synopsis

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.
