Modification of polybutadiene by transition metal catalysts: Hydroacylation of polybutadiene

The vinyl groups in polybutadiene are hydroacylated in the presence of a transition metal complex to give acylfunctionalized polybutadiene. Aldimine, aldehyde, and primary alcohol can be used for hydroacylation as substrates. It is noteworthy that the hydrogenation of double bonds as well as hydroacylation are achieved when primary alcohol is used. A variety of functional groups, including acylferrocenyl, benzoyl and acylheteroaromatic, are incorporated into the polymer backbone. The modified polymers are characterized by ¹H NMR, ¹³C NMR, and IR spectroscopy. The brief overviews on the other modification methods are also presented.
