Decarboxylative, Radical C–C Bond Formation with Alkyl or Aryl Carboxylic Acids: Recent Advances

Abstract The ubiquity of carboxylic acids as naturally derived or man-made chemical feedstocks has spurred the development powerful, decarboxylative C–C bond-forming transformations for organic synthesis. Carboxylic benefit not only from extensive commercial availability, but are stable surrogates organohalides organometallic reagents in transition-metal-catalysed cross-coupling. Open shell reactivity (or derivatives thereof) to furnish carbon-centred radicals is proving transformative synthetic chemistry, enabling novel and strategy-level C(sp3)–C bond disconnections with exquisite chemoselectivity. This short review will summarise several latest advances this ever-expanding area. 1 Introduction 2 Improved Decarboxylative Arylations 3 sp3–sp3 Cross-Coupling Acids Aliphatic Bromides 4 Alcohols Amines 5 Doubly 6 Bond Formation (Hetero)aryl 7 Conclusions
