摘要:

在三氟甲磺酸银的催化下,二苯二硒醚被1-氯甲基-4-氟-1,4-二氮杂双环[2.2.2]辛烷二(四氟硼酸盐)(Selectfluor)氧化后,分别与1-己烯烃、苯乙烯或其衍生物加成;在含有水或醇(如甲醇、乙醇、异丙醇)的二氯甲烷中(二氯甲烷与水或醇的体积比为1:1)反应,分别得到β-羟基或β-烷氧基苯硒醚,产率为72%~94%;探讨了反应条件及底物的适用范围。 此方法具有反应条件温和、产率高的特点。

Abstract:

Diphenyl diselenide was oxidized by Selectfluor and added to alkenes catalyed by silver triflate. The reaction performed in CH2Cl2 in the presence of water or alcohol leading to β-hydroxy or β-alkoxy selenides in good yields in the range of 72%~94%. The reaction conditions and the scope of substrates were discussed. This method has some advantages such as mild reaction conditions and high yields.
