Synthesis of Sulfones


Recent Literature

In a palladium catalyzed Negishi-type α-arylation of sulfones and sulfonamides with a broad range of aryl bromides, the substrates are selectively metalated in situ with tmp·ZnCl·LiCl base and cross-coupled in the presence of a catalyst system that is generated from Pd(dba)2 and XPhos.

Ni-catalyzed stereoconvergent Negishi arylations and alkenylations of racemic α-bromosulfonamides and -sulfones furnish cross-coupling product in very good ee and yield for an array of reaction partners. Mechanistic studies are consistent with the generation of a radical intermediate.
