Thiosilane and a catalytic amount of a Bronsted acid mediate the novel domino-type rearrangement reaction of the 4,4-disubstituted cyclohexadienones to produce the 3,4-disubstituted benzenethioethers; the key step is 1,2-addition of thiosilane to dienone.
硫代硅烷和催化量的布朗斯台德酸介导4,4-二取代的环己二酮的新型多米诺型重排反应,生成3,4-二取代的苯硫醚。关键步骤是将1,2-硫代硅烷添加到二烯酮中。
