A transition-metal-free decarboxylative thiolation protocol is reported in which primary, secondary, tertiary (hetero)aryl acetates and α-CN substituted acetates undergo the decarboxylative thiolation smoothly, to deliver a variety of functionalized aryl alkyl sulfides in moderate to excellent yields. Aryl diselenides are also amenable substrates for construction of C-Se bonds under the simple and mild reaction conditions. Moreover, the protocol is successfully applied to the late-stage modification of pharmaceutical carboxylates with satisfactory chemoselectivity and functional-group compatibility. This journal is
Arylthio-metal exchange of α-arylthioalkanenitriles

The addition of BuLi, Bu3MgLi, Et2ZnBuLi, or Me 2CuLi to α-arylthioalkanenitriles triggers an arylthio-metal exchange. NMR spectroscopic analyses implicate organometallic attack on sulfur forming a three-coordinate sulfidate as the key intermediate. Electrophilic trapping affords tertiary and quaternary nitriles in high yield. The method addresses the challenge of improving the functional group tolerance and preventing polyalkylations.

Adding organolithiums, Grignard reagents, or zincates to sulfinylnitriles triggers a facile sulfinyl-metal exchange to afford N- or C-metalated nitriles. Sulfinyl-magnesium exchange-alkylations efficiently install quaternary and tertiary centers, even in
Nitrile alkylations through sulfinyl-metal exchange

Triple alkylation: Phenylsulfinyl- and phenylthioacetonitrile can function as trianion equivalents of acetonitrile by sequential alkylation and sulfinyl-metal exchange (see scheme; mCPBA=meta-chloroperoxybenzoic acid). The metalated nitriles alkylate a range of electrophiles to obtain nitriles with quaternary centers. The sulfinyl-metal exchange proceeds under very mild conditions and has a high functional-group tolerance. Copyright
