| Abstract: | The properties of the ruthenium (II) phosphine complexes Ru(dppe)2(OTs)2] and Ru{PhP(CH2CH2CH2PPh2)2}(OTs)2] as catalysts of alternating copolymerization of ethylene and carbon monoxide were studied. The catalytic activity of these
complexes in the absence of cocatalysis is low, but it is substantially increased in the presence of trifluoroacetic acid
or 1,4-benzoquinone. These compounds are the first ruthenium complexes which catalyze copolymerization of ethylene and CO.
