Provided is a process for converting an alkane to an alkene. The process comprises (a) contacting the alkane and either (i) an oxidizing electrophile comprising a main group element in oxidized form, or (ii) an oxidant and a reduced form of the oxidizing electrophile, in a liquid medium comprising an oxygen acid and optionally one or more additives selected from a non-oxidizable liquid, a salt additive, a Lewis acid, and water, to provide an oxidized intermediate and a reduced form of the oxidizing electrophile; (b) optionally separating the oxidized intermediate and the reduced form of the oxidizing electrophile; and (c) performing an elimination reaction on the oxidized intermediate to provide the alkene and the oxygen acid.
本发明提供了一种将烷烃转化为烯的工艺。该工艺包括:(a) 将烷烃和(i) 由氧化形式的主族元素组成的氧化亲电子体,或(ii) 氧化剂和还原形式的氧化亲电子体,在包括氧酸和任选选自非氧化性液体、盐添加剂、路易斯酸和水的一种或多种添加剂的液体介质中接触,以提供氧化中间体和还原形式的氧化亲电子体;(b) 有选择地分离氧化中间体和还原形式的氧化亲电子体;以及 (c) 对氧化中间体进行消除反应,以提供烯和氧酸。
