N2 - The preparation of imidazolinium salts, which can be used as precursors of pincer-type N-heterocyclic carbene ligands, is described. The formation of imidazolinium salts under standard conditions is difficult, but they have been successfully synthesized by reaction of the corresponding diamines and trimethyl orthoformate in 1,1,1,3,3,3-hexafluoroisopropanol. The synthesis of new chiral C2 symmetric imidazolinium salts is also described.
