Copper-catalyzed oxidative S-arylation of 1,2-bis(o-amino-1H-pyrazolyl) disulfides with arylboronic acids for the synthesis of (o-amino-1H-pyrazolyl)aryl sulfides has been developed in the presence of CuI, 1,10-phenanthroline, and O2. A variety of dipyrazolyl disulfides bearing free NH2 groups underwent the reaction with arylboronic acids efficiently to selectively afford the corresponding S-arylation products
在存在下,已开发了铜催化的1,2-双(邻氨基-1 H-吡唑基)二硫化物与芳基硼酸的氧化S-芳基化反应,用于合成(邻氨基-1 H-吡唑基)芳基硫化物。 CuI,1,10-菲咯啉和O 2。各种带有游离NH 2基团的二吡唑基二硫化物与芳基硼酸有效地反应,以中等至极好的收率选择性地提供相应的S-芳基化产物。值得注意的是,氨基被很好地耐受,并且制备了一系列氟虫腈类似物。 铜-1,10-菲咯啉-S-芳基化-1,2-双(邻氨基-1 H-吡唑基)二硫化物-芳基硼酸-(邻氨基-1 H-吡唑基)芳基硫化物
