Diethoxy disulfide (1) reacted with arylhydrazines to give arylbenzenes, diaryl sulfides, and aryl ethoxy tetrasulfides. The reaction of 1 with hydrazobenzenes gave azobenzenes in quantitative yields. The treatment of 1 with 1,5-diphenylthiocarbonohydrazide or 1,5-diarylthiocarbazones afforded 2,3-diaryltetrazolium-5-thiolates.

A catalyst- and metal-free hydrogenation of azobenzenes to hydrazobenzenes in the presence of thioaceticacid was achieved under visible light irradiation. The transformation was carried out under mild conditions in an air atmosphere at ambient temperature, generating a variety of hydrazobenzenes with yields up to 99%. The current process is compatible with a variety of substituents and is highly chemoselective

A highly efficient copper(I)-catalyzed approach for the synthesis of 1,1′-bisindoles that is based on the formation of four bonds in one step has been developed. The unprecedented three component reaction between one molecule of a 1,2-bis(2-bromoaryl)hydrazine and two molecules of a 1,3-diketone employing 10 mol% CuI as a catalyst and Cs2CO3 as a base in DMSO at 100 °C for 24 h delivers substituted
开发了一种高效的铜 ( I ) 催化合成 1,1'-双吲哚的方法,该方法基于一步形成四个键。采用 10 mol% CuI 作为催化剂,Cs 2 CO 3作为碱,在 DMSO 中,一分子 1,2-双(2-溴芳基)肼和两分子 1,3-二酮之间发生前所未有的三组分反应。100°C 24 小时可得到取代的 1,1'-双吲哚,收率高达 92%。新方法采用双多米诺缩合/乌尔曼型 C-C 耦合。它允许从容易获得的起始材料一步有效且实用地获得取代的 1,1'-双吲哚。
