Carboxylation of C-H bonds using N -heterocyclic carbene gold(I) complexes

supporting information; experimental part, p. 8858 - 8859 (2010/08/21)
A highly efficient [(NHC)AuI]-based (NHC = N-heterocyclic carbene) catalytic system for the carboxylation of aromatic and heteroaromatic C-H bonds was developed. The significant base strength of the Au-OH species is at the origin of the activation process and permits the facile functionalization of C-H bonds without the use of other organometallic reagents.
