Abstract

A pseudo-in situ research method was applied to provide insight into the structural evolution of carbon in an Fe@C catalyst at different stages of the Fischer–Tropsch reaction. Five typical stages of the catalyst were selected for in-depth structural investigation; these were: the fresh catalyst, reduced catalyst, and catalyst in the stable conversion period, in an increased-conversion period and at the inactivation stage. The results indicated that the integral structure of Fe@C constantly changed in the Fischer–Tropsch reaction. Iron carbide transformed from the Fe phase that was easily oxidized under high temperature Fischer–Tropsch conditions, and the carbon framework was completely destroyed in the reaction process, leading to a drastic decrease in the specific surface area of the material. This destruction could have two opposing effects: on the one hand, the loss of carbon could re-expose the active sites that have been covered by carbon at a reaction temperature of 320 °C and favor the reaction; on the other hand, the deposition of carbon could block the active sites and lead to inactivation when the reaction temperature is over 340 °C.

Eco-friendly decarboxylative cyclization in water: practical access to the anti-malarial 4-quinolones

Abstract

An environmentally benign decarboxylative cyclization in water has been developed to synthesize 4-quinolones from readily available isatoic anhydrides and 1,3-dicarbonyl compounds. Isatins are also compatible for the reaction to generate 4-quinolones in the presence of TBHP in DMSO. This protocol provides excellent yields under mild conditions for a broad scope of 4-quinolones, and has good functional group tolerance. Only un-harmful carbon dioxide and water are released in this procedure. Moreover, the newly synthesized products have also been selected for anti-malarial examination against the chloroquine drug-sensitive Plasmodium falciparum 3D7 strain. 3u is found to display excellent anti-malarial activity with an IC₅₀ value of 33 nM.

Development of an SNAr Reaction: A Practical and Scalable Strategy To Sequester and Remove HF

ORGANIC CHEMISTRY SELECT

A simple and operationally practical method to sequester and remove fluoride generated through the S_NAr reaction between amines and aryl fluorides is reported. Calcium propionate acts as an inexpensive and environmentally benign in situ scrubber of the hydrofluoric acid byproduct, which is simply precipitated and filtered from the reaction mixture during standard aqueous workup. The method has been tested from 10 to 100 g scale of operation, showing >99.5% decrease in fluoride content in each case. Full mass recovery of calcium fluoride is demonstrated at both scales, proving this to be a general, efficient, and robust method of fluoride abstraction to help prevent corrosion of glass-lined reactors.
