CARBOXYLATION CATALYSTS
The use of a complex of the form Z—M—OR in the carboxylation of a substrate is described. The group Z is a two-electron donor ligand, M is a metal and OR is selected from the group consisting of OH, alkoxy and aryloxy. The substrate may be carboxylated at a C—H or N—H bond. The metal M may be copper, silver or gold. The two-electron donor ligand may be a phosphine, a carbene or a phosphite ligand. Also described are methods of manufacture of the complexes and methods for preparing isotopically labelled caboxylic acids and carboxylic acid derivatives.

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

Carboxylation of N-H/C-H bonds using n-heterocyclic carbene copper(I) complexes
Greenhouse gas makes good: A simple copper-mediated protocol has been developed where N-H or C-H bonds can be directly functionalized using an easily prepared catalyst. The novel [1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene] copper(I) hydroxide, [Cu(IPr)(OH)], permits the facile activation and carboxylation of N-H and C-H bonds with pKavalues of less than 27.7 (see scheme).
