Abstract
Using a combination of heteropoly acids such as H3PMo12O40 or H3PW12O40 with cetylpyridinium chloride as the catalyst, olefins such as (I) and (IV), and allylic alcohols, e.g. (VI), are oxidized with hydrogen peroxide (II) to give the epoxides (III), (V), and (VII).
ChemInform Abstract
Using a combination of heteropoly acids such as H3PMo12O40 or H3PW12O40 with cetylpyridinium chloride as the catalyst, olefins such as (I) and (IV), and allylic alcohols, e.g. (VI), are oxidized with hydrogen peroxide (II) to give the epoxides (III), (V), and (VII). With the same oxidation system, secondary alcohols such as (VIII) are converted into ketones; the vic-diol (X) and the olefin (XII) are transformed into the acid (XI).
