摘要
苯硫酚或苯甲硫醇在CuI/Phen催化下,以Na2CO3为碱,乙二醇二甲醚为溶剂,在氮气保护下,回流搅拌可得二芳基二硫醚,收率为79%-99%;在Ni（PPh3）2Cl2催化下,以K2CO3为碱,得到的二芳基二硫醚的收率为77%-86%;在FeCl3/L-Proline催化下,以K2CO3为碱,甲醇为溶剂时,在氮气保护下,回流搅拌得到二芳基二硫醚,收率为86%-97%.为合成二芳基二硫醚提供了3种有效方法。
Various symmetric diaryldisulfides were synthesized from commercially available aryl thiols catalyzed by CuI/Phen with Na2CO3 as a base in dimethoxyethane（DME）,and stirred and refluxed under the nitrogen atmosphere for high yields of 79%to 99%.In the presence of Ni（PPh3）2Cl2 with K2CO3 as a base under the nitrogen atmosphere,diaryldisulfides can be synthesized from aryl thiols in DME,whose yields are at the range of 77% to86%.Diaryldisulfides can also be synthesized from aryl thiols catalyzed by FeCl3/L-Proline with K2CO3 as a base in MeOH,and its yields are at the range of 86%to 97%.In this paper,we present three methods for the preparation of diaryldisulfides.
