Sulfones are excellent candidates for the design of new C–C and C–X bond-forming reactions owing to the easy activation of C–S bonds. This review focuses on challenges and recent opportunities for catalytic functionalization of sulfones.
A palladium-catalyzed stereospecific ring-opening arylation of α-aminoaryl-tethered alkylidenecyclopropanes for the stereoselective synthesis of 1,1,2-trisubstituted conjugated dienes has been developed.
An in situ Pd doped conjugated polymer network-based efficient photocatalyst has been developed to carry out Suzuki type cross coupling reaction under visible light or sunlight.
A mechanochemically induced, nickel-catalyzed one-pot multicomponent protocol for a direct arylative detrifluoromethylation of ArCF3 is described. This reaction represents the first example of C–C coupling with CF3 as a leaving group.
Phosphinoferrocene ligands equipped with flexible heterocyclic pendants coordinate Pd(II) preferably via the phosphine group; coordination of the N-heterocyclic groups leads to dimeric or chelate complexes depending on the ligand type.
