Abstract
Functionalization of perfluoroalkyl compounds has shown huge potential in synthetic chemistry and drug development. Herein, we report a one-pot tandem perfluoroalkylation-defluorination reaction of indole, perfluoroalkyl iodide, and water in the presence of Na2S2O4. A wide array of indole derivatives were efficiently accessed with good yields under mild reaction conditions. The reaction is believed to undergo perfluoroalkylation and follow the defluorination hydrolysis pathway. This study represents an alternative approach for defluorination functionalization.

Abstract
A nickel-catalyzed direct cross-coupling of unactivated aryl fluorides with aryl bromides is realized. The one-pot reaction, which avoids the use of preformed and sensitive organometallic reagents, proceeds effectively via C-F bond cleavage at room temperature in THF in the presence of the phosphine ligand and magnesium powder (with or without TMSCl) to produce the desired biaryls in modest to good yields.

Abstract
Few methods are known for the synthesis of nitroindole derivatives. A simple and practical Cs2CO3-promoted method for the synthesis of 6-nitroindole derivatives from enaminones and nitroaromatic compounds has been developed. Two new C-C and C-N bonds were formed in a highly regioselective manner under transition metal-free conditions.
