Ov. Gusev et al., Ruthenium phosphine complexes as catalysts of alternating copolymerizationof ethylene and carbon monoxide, RUSS CHEM B, 49(6), 2000, pp. 1113-1115
The properties of the ruthenium(II) phosphine complexes [Ru(dppe)(2)(OTs)(2
)] and [Ru{PhP(CH2CH2CH2PPh2)(2)}(OTs)(2)] as catalysts of alternating copo
lymerization of ethylene and carbon monoxide were studied. The catalytic ac
tivity of these complexes in the absence of cocatalysts is low, but it is s
ubstantially increased in the presence of trifluoroacetic acid or 1,4-benzo
quinone. These compounds are the first ruthenium complexes which catalyze c
opolymerization of ethylene and CO.
