[reaction: see text] A versatile approach to ketone synthesis is described. The reaction relies on the palladium-catalyzed, copper diphenylphosphinate-mediated coupling of thiol esters with organostannanes under neutral reaction conditions. This reaction complements the previously described coupling of thiol esters with boronic acids that used dual thiophilic-borophilic activation methodology.

cross-coupling reactions of thioesters by selective acyl C(O)–S cleavage have emerged as a powerful platform for the preparation of complex molecules. Herein, we report divergent Liebeskind–Srogl cross-coupling of thioesters by Pd–NHC (NHC = N-heterocycliccarbene) catalysis. The reaction provides straightforward access to functionalized ketones by highly selective C(acyl)–S cleavage under mild conditions. Most
