A palladium/copper-cocatalyzed Ullmann-type N-arylation of anilines using alkyl(aryl)sulfonium triflates as arylation reagents has been accomplished. The reaction enabled Caryl-S bond cleavage over Calkyl-S bond breakage of alkyl(aryl)sulfoniums by Pd(P(tBu)3)2/CuI and gave the corresponding N-arylated products in good to high yields. It was also significant that the reactions of aniline with asymmetric butyl(mesityl)(aryl)sulfonium triflates showed excellent selectivity, in which the aryl groups other than the bulky and electron-rich mesityl moieties were transformed.
Cu-Catalyzed Coupling of Aryl Iodides with Thiols Using Carbonyl-Phosphine Oxide Ligands

A series of carbonyl-phosphine oxide ligands were synthesized from 2-bromophenylaldehyde and used in Cu-catalyzed C-S coupling reactions. Aryl iodide and aryl bromide reacted with thiols efficiently upon catalysis under mild reaction conditions and a yiel
