A new type of ruthenium carbene complexes with N-chelating ligand

N-chelate ruthenium carbene complexes in olefin metathesis and isomerization

“…Complexes 1-3 were synthesized according to the procedures described in [5][6][7], respectively; the syntheses were carried out under argon in an MBraun glove box. Presumably, analogous processes take place in the presence of complex 2.…”

“…The catalytic activity of recently reported complexes 1 [5] and 2 [6] containing an N-chelating benzylidene ligand has been studied only in ring-opening metathesis polymerization and ring-closing metathesis [5,6]. The behavior of these complexes in cross metathesis was not described, and their effect on the isomerization during metathesis was not studied; these issues were the subjects of the present study.…”
