Tetrafunctional silyl enol

On the basis of these studies, a tetrafunctional silyl enol ether (18) carrying four such enolate functions has been prepared the corresponding trifunctional compound is also available [142]. These silyl enolates effectively couple living poly(vinyl ethers) with the chloride counteranion to form tri- and tetraarmed polymers (e.g., 19, Scheme 10) [205]. Similar chemistry also operates with living cationic poly(a-methylstyrene) but specifically needs the additional use of an amine to accelerate the release of the trimethylsilyl groups [159,207]. [Pg.417]
