aryl halides with the thiourea anion afford arene thiolate ions in DMSO. These species without isolation, and by a subsequent aliphatic nucleophilic substitution, S(RN)1 reaction, oxidation, or protonation, yield aryl methyl sulfides, diaryl sulfides, diaryl disulfides, and aryl thiols with good yields (50-80%). This is a simple and convenient approach which involves the use of the commercially available
[反应:请参见文字]。芳基卤化物与硫脲阴离子的光诱导反应在DMSO中提供了芳烃硫醇盐离子。这些物质无需分离,并通过随后的脂族亲核取代,S(RN)1反应,氧化或质子化,可制得芳基甲基硫化物,二芳基硫化物,二芳基二硫化物和芳基硫醇,收率良好(50-80%)。这是一种简单方便的方法,涉及在“一锅”两步法中合成芳族硫化合物时使用市售的廉价硫脲。
