Unprecedented directed lateral lithiations of tertiary carbons on NHC platforms

5 February, 2015 - 17:17

Chem. Commun., 2015, 51,3049-3052
DOI: 10.1039/C4CC08434A, CommunicationAndreas A. Danopoulos, Pierre Braunstein, Elixabete Rezabal, Gilles Frison
Deprotonation of the tautomeric mixture of 4-amido-imidazoliums and 4-amino-N-heterocyclic carbenes led to dilithiated dianionic functional NHCs, via an unprecedented regioselective, directed remote lateral lithiation of a tertiary CHMe2 carbon. DFT calculations support that the nature of products is under thermodynamic control.
