Streszczenie

The ruthenium(II)-N-heterocyclic carbene complex, [RuCl2(1-butyl-3-methylimidazol-2-ylidene)(p-cymene)] selectively catalyzes oligomerization of phenylacetylene (PA) and its derivatives to linear oligomers, containing positively charged imidazolium end-group and uncharged ones. The charged oligomer chain consists of maximum 9–11 PA monomer units after 36 h reaction at 80 °C whereas mainly pentamers are formed as other products. The H2 atmosphere retards oligomerization of PA and hydrogenation to vinylbenzene and ethylbenzene is observed instead.
