hydroperoxides were developed by using zeolite-confined osmium(0) nanoclusters as reusable catalyst and without using any co-oxidant (H2O2, tBuOOH, NMO, etc.) in water/acetone (v/v = 1/4) mixture at room temperature. In this method, the oxygen atom of the allylic hydroperoxide group was transferred to the double bond of the same molecule via zeolite-confined osmium(0) nanoclusters. The method has been successfully
通过使用沸石限制的(0)纳米簇作为可重复使用的催化剂且不使用任何助氧化剂,开发了一种简便,高效且环保的方法,可从烯丙基氢过氧化物一锅法合成1,2 / 3-三醇( ħ 2 Ó 2,吨在室温下,在水/丙酮(v / v = 1/4)混合物中加入BuOOH,NMO等。在这种方法中,烯丙基氢过氧化物基团的氧原子通过沸石限制的(0)纳米簇转移到同一分子的双键上。该方法已成功应用于各种烯丙基氢过氧化物,并以高化学收率获得了相应的1,2 / 3-三醇。此外,提出了一种可行的机理,用于在沸石-Os 0催化剂存在下将烯丙基氢过氧化物催化氧化为相应的1,2 / 3-三醇,收集通过在沸石存在下测试各种烯丙基氢过氧化物而收集的所有结果。 -Os 0催化剂。
