A chemoselective and green reduction of nitro arenes to aromatic amines with FeSO4, NaBH4, H3PW12O40 in water at room temperature
A new efficient and practical method for the room-temperature reduction of aromatic nitro compounds employing FeSO4. 7H2O, NaBH4, H3PW12O40 system in H2O under mild conditions is reported. The method is simple, inexpensive, easily scaled-up and applicable for the large scale preparation of different substituted anilines.

متن کاملPalladium-Catalyzed Acetylation of Arenes
A simple method for the preparation of aryl methyl ketones is reported. The transformation involves the Pd-catalyzed coupling of an acyl anion equivalent, acetyltrimethylsilane, with aryl bromides to afford the corresponding acetylated arenes in synthetically useful yields. The methodology is tolerant of heterocycles and provides a new method for arene functionalization.
متن کاملEnforced stacking in crowded arenes.
Disk-shaped π-surfaces that stack to form columnar structures1 are prototypes of molecular-scale wires that have an insulating hydrocarbon sheath surrounding a conductive aromatic core.2 Typically, the strengths of the associations between the molecules, formed through contacts between aromatic surfaces, are weak. Previous schemes to modulate these strengths are based on metalligand interaction...
متن کاملCu(I)-mediated (18)F-trifluoromethylation of arenes: rapid synthesis of (18)F-labeled trifluoromethyl arenes.
This report is concerned with an efficient, Cu(I)-mediated method for the radiosynthesis of [(18)F]trifluoromethyl arenes, abundant motifs in small molecule drug candidates and potential radiotracers for positron emission tomography. Three (18)F-labelled radiotracer candidates were synthesised from [(18)F]fluoride ions as proof of principle. The new protocol is widely applicable for the synthes...
