Copper-catalyzed decarboxylative thiolation using molecular oxygen as the sole oxidant was developed. A variety of aromatic carboxylic acids including 2-nitrobenzoic acids, pentafluorobenzoic acid and several heteroaromatic carboxylic acids undergo efficient thiolation to furnish the aryl sulfides in moderate to excellent yields.

Ligand-free solid-supported nano and microparticles of Pd(0) (SS-Pd) were used as a heterogeneous catalyst in carbon-heteroatom bond formation reactions. Nitro substituted aryl halides reacted with oxygen, sulfur, and nitrogen nucleophiles to afford the corresponding products in good yields. A one-pot sequential cross coupling and nitro-reduction was also performed using the same SS-Pd catalyst to access amine substituted carbon-heteroatomic molecules. In addition, SS-Pd could be recycled up to seven runs without a significant loss of catalytic activity.
The [Cu]-catalyzed SNAR reactions: Direct amination of electron deficient aryl halides with sodium azide and the synthesis of arylthioethers under Cu(II) - Ascorbate redox system

experimental part, p. 7642 - 7650 (2010/12/19)
A one pot [Cu]-promoted SNAr reaction of electron-deficient halobenzenes with sodium azide and the reduction of the intermediate aryl azides under the same Cu(II)-ascorbate redox conditions leading to anilines has been documented. Control experiments revealed that both ascorbate and proline play important role in the reaction path way. Further, the use of this catalytic Cu(II)-ascorbate redox system has been explored for the synthesis of arylthioethers.
A highly regioselective reaction of N-fluoropyridinium salts with stabilized sulfur, oxygen, and nitrogen nucleophiles: A convenient route to 2-substituted pyridines

2-Substituted pyridines are efficiently obtained by the reactions of N- fluoropyridinium tetrafluoroborate or triflate with anions derived from benzenethiols, phenols, azoles, cyanamide, and with azide anion. The results are consistent with a nucleophile addition at the position 2 of the N- fluoropyridinium cation as the major reaction pathway.
