A simple high-yielding preparation of aryl alkynyl sulfides is presented. The reaction of a chloroacetylene with a thiolate salt in the presence of an amine mediator (dimethylamine or N,N′-dimethylethylenediamine) yields the alkynyl sulfides in excellent yields. The alkynyl chloride is easily prepared from the parent alkyne.
一种简单高产率的芳基炔基硫醚的制备方法被提出。在胺介质(二甲胺或N,N'-二甲基乙二胺)存在下,氯代乙炔与硫醇盐反应可高产率地生成炔基硫醚。炔基氯化物可从母体炔烃轻松制备。
