DESCRIPTION:Nitin T. Patil\n \nTraditionally\, gold complexes have been r
 ecognized as Lewis acid catalysts for the activation of C-C multiple bonds
  (Scheme\, LHS). Over the years\, there has been a considerable shift\, an
 d Au(I)/Au(III) redox catalysis is now recognized as an established techni
 que for achieving cross-coupling reactivities (Scheme\, RHS). The pioneeri
 ng work by Zhang and Toste group revealed the role of external oxidants to
  overcome the high redox potential of Au(I)/Au(III) couple (E0 = +1.41 V) 
 and to facilitate two-electron redox cycle in gold catalysis. Later\, the 
 Glorius group introduced the merged gold/photoredox strategy to circumvent
  the need for a stoichiometric oxidant in these processes. The Waser group
  showed that ethynylbenziodoxolones (EBXs) acts as both an oxidant and an 
 alkyne surrogate\, enabling redox gold catalysis.\n\nAll the above strateg
 ies were not amenable to the use of aryl halides\, and thus their use in g
 old-catalyzed cross-coupling reactions remained forbidden. In recent years
 \, ligand-enabled gold-catalyzed organic reactions have emerged as a valua
 ble tool\, allowing for the use of aryl halides as cross-coupling partners
 . In this talk\, I will discuss our most recent work on alkene functionali
 zation employing cross-coupling reactivities.\n\nReferences\n1. a) A. Kuma
