The ability of N-heterocyclic carbenes to promote O-to-C carboxyl transfer on a range of indolyl and benzofuranyl carbonates is examined, and the scope and limitations of this process delineated.

The structural requirements of amidines necessary to act as efficient O- to C-carboxyl transfer agents are delineated and the scope of this process outlined through its application to a range of oxazolyl, benzofuranyl and indolyl carbonates.
