presence of cesium carbonate, a variety of aldehydes can be epoxidized directly with allyl bromide at 50°C under solid-liquid phase transfer condition by use of a catalytic amount of diisobutyl telluride to afford vinyl epoxides in good yields with predominant cis stereoselectivity.
在碳酸铯的存在下,可以通过使用催化量的二异丁基碲化物,在固液相转移条件下于50°C用烯丙基溴直接环氧化各种醛,从而以良好的收率和主要的顺式立体选择性获得乙烯基环氧化物。
