The ylide epoxidation catalyzed by telluronium salts provides a simple and extremely efficient route to vinyl epoxides in excellent yields. Both aromatic and aliphatic aldehydes work well. The best results were obtained by using 2 mol% of telluronium salts with Cs2CO3 in t-BuOH.

trans- or cis-β-Trimethylsilylvinyloxiranes are prepared by the reaction of aldehydes with a 3-trimethylsilylated dimethylsulfonium allylide under phase-transfer conditions or with a preformed 3-trimethylsilylated diphenylsulfonium allylide in the presenc
A convenient and stereoselective synthesis of trimethylsilylvinyl oxiranes via silylated telluronium allylide+

Trimethylsilylated diisobutyltelluronium allylide, a moderately stabilized telluronium ylide, generated from 3-trimethylsilyl-2-propenyldiisobutyltelluronium bromide (3) with LiTMP, reacted with carbonyl compounds to afford trimethylsilylvinyl oxiranes in excellent yields with high syn stereoselectivity.
