several techniques including FT-IR, XRD, EDX and scanning electron microscopy. The MOF-199 used as an efficient catalyst for one-pot synthesis of thiols by domino reactions of aryl halides and thiourea, and subsequently conversion to aryl alkyl sulfides and diaryl disulfides in polyethylene glycols (PEGs). A variety of aryl alkyl sulfides can be obtained in good to excellent yields in a relatively short
摘要 通过 1,3,5-苯三羧酸和 Cu 的反应合成了一种高度多孔的金属有机骨架 Cu3 BTC2(铜(II)-苯-1,3,5-三羧酸盐),即 MOF-199。 (OAc)2·H2O 采用溶剂热法,并通过多种技术进行表征,包括 FT-IR、XRD、EDX 和扫描电子显微镜。MOF-199 用作一锅法合成硫醇的有效催化剂,通过芳基卤化物和硫脲的多米诺反应,随后在聚乙二醇 (PEG) 中转化为芳基烷基硫化物和二芳基二硫化物。在相对较短的反应时间和痕量催化剂的存在下,可以以良好到极好的收率获得各种芳基烷基硫化物。此外,催化剂可以通过倾析与反应混合物分离,且可重复使用而不会显着降低催化活性。图形概要
