Charge-enhanced thiourea catalysts as hydrogen bond donors for Friedel?Crafts Alkylations

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

Catalytic and conductivity studies in two dimensional coordination polymers built with a thiazole based ligand

The employment of the commercial available organic ligand 2-mercapto-4-methyl-5-thiazoleacetic acid (H2L) in Zn and Cd chemistry yields two-dimensional (2D) coordination polymers (CPs) with pseudopolymorphic character. Thermal, catalytic and co

Quantification of Catalytic Activity for Electrostatically Enhanced Thioureas via Reaction Kinetics and UV-vis Spectroscopic Measurement

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

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

Water-soluble (salicyladimine)2Cu complex as an efficient and renewable catalyst for Michael addition of indoles to nitroolefins in water

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.

Carbohydrate-based tolylsulfonyl hydrazines: Effective catalysts for Michael addition of indoles to electron-deficient olefins in water

Carbohydrate-based tolylsulfonyl hydrazines were used for the first time to catalyze the Michael reaction of indoles to electron-deficient olefins in aqueous media to afford 3-substituted indole derivatives in good to excellent yields at room temperature.
