Heavy alkali metal complexes of N-heterocyclic carbenes
N-Heterocyclic carbene complexes of alkali metals (M = Na, K, Rb, Cs) were prepared from the zwitterionic trimethylsilylimidazolium borate [(C<sub>6</sub>F<sub>5</sub>)<sub>3</sub>B(IDipp)SiMe<sub>3</sub>] (1) by reaction with the corresponding alkali metal <i>tert</i>-butoxides MO<i>t</i>Bu. The alkali metal complexes were isolated as tetrahydrofuran (THF) solvates of the type [(C<sub>6</sub>F<sub>5</sub>)<sub>3</sub>B(IDipp)M(THF)<sub><i>x</i></sub>, 2M(THF)<sub><b><i>x</i></b></sub>, and their molecular structures were determined by single-crystal X-ray diffraction analysis.
