Method for realizing Glaser coupling reaction through sunlight catalysis

The invention discloses a method for realizing a Glaser coupling reaction through sunlight catalysis. The method mainly comprises the following steps that an alcohol compound is taken as a solvent, under the normal temperature and normal pressure conditions, a Cu(II) salt serves as a catalyst, a base compound is added, continuous stirring is conducted under sunlight irradiation, and thus a self-coupling reaction of a phenylacetylene compound can be achieved. The reaction does not involve any harsh and dangerous condition and can be conducted at the normal temperature and normal pressure; and the adopted catalyst is the Cu(II) salt which is stable in air, free of toxicity and low in cost, the reaction steps are simple, the condition is mild and safe, smooth conducting of the Glaser couplingreaction can be stably achieved, and safety, environmental protection and reliability of the reaction process are greatly improved. 本发明公开了一种通过太阳光催化实现Glaser偶联反应的方法，主要包括以下步骤：以醇类化合物为溶剂，在常温常压条件下，以Cu(II)盐作为催化剂，加入碱类化合物，在太阳光照射下不断搅拌
