Imidazoliidinium, tetrahydropyrimidinium and benzimidazolium. salts were prepared. Upon reaction with tBuOK, they generate carbene ligands, which were associated in situ to [RuCp*(MeCN)(3)]PF6 to produce ruthenium catalysts that are active for the substitution of allylic substrates by dimethyl of the N-heterocyclic structures, as well as that of the benzyhc N-substituents, on the reactivity and regioselectivity were examined.
