A novel and facile visible-light-mediated alkylation of indoles and nitroalkenes has been developed. In this protocol, rose bengal acts as a photosensitizer, and environmentally benign water was used as the green and efficient reaction medium. Indoles rea

Charge-enhanced catalysis has emerged as a powerful alternative to the mainstream use of neutral catalysis. With this in mind, we report a catalytic Friedel?Crafts alkylation method catalyzed by a charged thiourea incorporating a cationic cyclopropenium m

Charged thiourea derivatives containing one and two methylated or octylated pyridinium ion centers and a tetraarylborate or triflate counteranion are reported. These novel catalysts are much more active in the Friedel-Crafts reactions of trans-β-nitroalke

An efficient and environmentally friendly protocol has been demonstrated for water-soluble (salicyladimine)2Cu complex-catalyzed Michael addition of indoles to nitroolefins in water at 30 °C. A variety of substituted indoles and β-nitrostyrenes could be worked well to provide the title products in 81–97% yields. Moreover, the catalyst can be reused directly at least for four times without significantly decreasing activity.
De novo endo-functionalized organic cages as cooperative multi-hydrogen-bond-donating catalysts

Two endo-functionalized organic cages as oxyanion hole mimics were achieved via dynamic covalent chemistry, which exhibit good size selectivity, catalytic activity and broad substrate scopes for Friedel-Crafts reactions. The modular character of the synth
Friedel-crafts alkylation of indoles with nitroalkenes catalyzed by Zn(II)-thiourea complex
Wan, Ningning,Hui, Yonghai,Xie, Zhengfeng,Wang, Jide
experimental part, p. 311 - 315 (2012/04/23)
Friedel-Crafts alkylation of indoles with nitroalkenes catalyzed by a novel Zn(II)-thiourea complex has been developed. The remarkable advantages of this reaction are mild reaction conditions, simple workup procedure, high yield of products and the use of
