Summary:Successful dihydridocarbonyltris(triphenylphosphine)ruthenium (Ru-complex) catalyzed polymerization of 4-acetylstilbene with 1,3-divinyltetramethyldisiloxane to yield poly(3,3,5,5-tetramethyl-4-oxa-3,5-disila-1,7-heptanylene-alt-4-acetyl-3,5-stilbenylene) is reported. Polymerization results from Ru-complex catalyzed activation of aromatic C-H bonds which are ortho to the acetyl for selective anti-Markovnikov addition across the terminal C-C double bonds of 1,3-divinyltetramethyldisiloxane. The internal C-C double bond of 4-acetylstilbene does not react.
