A general protocol for the chemoselectivity-controlled C-C and C-S coupling reactions of di(hetero)aryl disulfides with Grignard reagents catalyzed by ferrocene and palladium acetate has been developed. Ferrocene favored the formation of C-S coupled products at low temperature, whereas C-C bond couplings were favored when palladium acetate was used. All the reactions proceeded with excellent chemoselectivity and in good yields under mild conditions, and a library of molecules with pyridine and pyrimidine scaffolds was produced. © 2015 WILEY-VCH Verlag GmbH & Co.

Pyrimidin-2-yl sulfonates, as an efficient reaction partner, which can be easily prepared from cheap commercial materials, were coupled with phenols and anilines to give a wide array of C2-aryloxy- and arylaminopyrimidines in good to excellent yields under mild reaction conditions.

An efficient method for carbon-carbon bond formation is described. The process employs the palladium-catalyzed copper-mediated cross-coupling of diheteroaryl disulfides with arylboronic acids or alkynes to deliver C-C coupling products through unreactive C-S bond cleavage. The scope of the coupling reactions, including both the disulfides and arylboronic acids or alkynes, are documented. © 2014 Wiley-VCH Verlag GmbH&Co. KGaA, Weinheim. Source

(2-Chlorobenzoyloxy)copper(I) exhibited high activity towards the challenging amination of 2-amino pyrimidines with aryl halides. Herein, secondary and tertiary amines were selectively produced by using potassium phosphate and sodium-t-butoxide. Potassium phosphate favored the formation of secondary amines, whereas tertiary amines were favored when sodium-t-butoxide was used. © 2015 Elsevier Ltd. All rights reserved. Source
