Description:
The novel dicationic metathesis catalyst [(RuCl 2 (H 2 ITapMe 2 )(=CH–2-(2-PrO)-C 6 H 4 )) 2+ (OTf − ) 2 ] ( Ru-2 , H 2 ITapMe 2 = 1,3-bis(2’,6’-dimethyl-4’-trimethylammoniumphenyl)-4,5-dihydroimidazol-2-ylidene, OTf − = CF 3 SO 3 − ) based on a dicationic N -heterocyclic carbene (NHC) ligand was prepared. The reactivity was tested in ring opening metathesis polymerization (ROMP) under biphasic conditions using a nonpolar organic solvent (toluene) and the ionic liquid (IL) 1-butyl-2,3-dimethylimidazolium tetrafluoroborate [BDMIM + ][BF 4 − ]. The structure of Ru-2 was confirmed by single crystal X-ray analysis. Beilstein J. Org. Chem. 2015, 11, 1632–1638. doi:10.3762/bjoc.11.178
