(Hetero)aroyl chlorides, alkynes, and ethyl 2-mercapto acetate can be reacted in a consecutive three-component synthesis to give 2,4-disubstituted thiophene 5-carboxylates in good to excellent yields. In the sense of a pseudo-five-component reaction highly blue luminescent symmetrical terthiophenes and a quinquethiophene can be synthesized in excellent yield.
(杂)芳酰氯、炔烃和乙基2-巯基乙酸酯可以在连续的三组分合成中反应,以良好至优异的产率得到2,4-二取代的噻吩5-羧酸酯。在伪五组分反应的意义上,高度蓝色发光的對稱三噻吩和五噻吩可以以优异的产率合成。
