描述了一种通过容易获得的二烯醇甲硅烷基醚与元素硫的反应合成噻吩衍生物的简便方法。二烯醇甲硅烷基醚和元素硫在 MS4A 存在下加热至 180 摄氏度时，生成 3-甲硅烷氧基噻吩衍生物，产率高达 98%。在该反应中，1,2-二噻因和八元环四硫化物可能形成噻吩衍生物。 (c) 2005 Elsevier Ltd. 保留所有权利。
A facile method for the synthesis of thiophene derivatives via the reaction of readily accessible dienol silyl ethers with elemental sulfur is described. Dienol silyl ethers and elemental sulfur, when heated at 180 degrees C in the presence of MS4A, provided 3-siloxythiophene derivatives in yields up to 98%. In this reaction, thiophene derivatives might be formed through 1,2-dithiines and eight-membered cyclic tetrasulfides. (c) 2005 Elsevier Ltd. All rights reserved.
