A FIRST EXAMPLE OF CATALYTIC YLIDE EPOXIDATION REACTION: FACILE SYNTHESIS OF VINYL EPOXIDES FROM ALDEHYDES CATALYZED BY DIISOBUTYL TELLURIDE
In the presence of cesium carbonate, a variety of aldehydes can be epoxidized directly with allyl bromide at 50 deg C under solid-liquid phase transfer condition by use of a catalytic amount of diisobutyl telluride to afford vinyl epoxides in good yields

A Facile Synthesis of α,β-Unsaturated Epoxides via Allyldi-isobutyltelluronium Bromide
In the presence of solid KOH, allyldi-isobutyltelluronium bromide 2 reacts directly with aromatic aldehydes at room temperature under solid-liquid phase-transfer conditions to afford α,β-unsaturated epoxides 3 in excellent yields.
