Efficient synthesis of unsymmetrical heteroaryl thioethers and chalcogenides by alkali hydroxide-mediated S<sub>N</sub>Ar reactions of heteroaryl halides and dichalcogenides
An efficient alkali hydroxide-mediated SNAr reaction of heteroaryl halides has been developed for the practical synthesis of the useful unsymmetrical heteroaryl thioethers and chalcogenides. The usually odorless, easily available, lowly toxic, and easily stored and handled diorganyl dichalcogenides can be used as safer and convenient chalcogen nucleophile precursors and diverse unsymmetrical heteroaryl
An efficient regioselective synthesis of 4-chalcogen-substituted arylamines by FeF3-catalyzed sulfenylation and selenation of arylamines has been developed. In the presence of FeF3 and I2, a variety of arylamines underwent the reaction with disulfides or diselenides to afford the corresponding 4-sulfenyl- or 4-selenenylarylamines in moderate to good yields.
