Hydrosilylation of unsaturated fatty acid N ‐phenyl amides

The synthesis and the characterization of new silylated fatty acid N ‐phenyl amides as novel precursors for structured materials are described. Hydrosilylation of vinylic groups in terminal N ‐phenyl unsaturated fatty amides was efficiently catalyzed by Karstedt's catalyst. Radical initiators have been found to be active for both terminal and internal double bonds of unsaturated fatty N ‐phenyl amides at the necessary condition to suppress initially the conjugation in the amide function, the anilide moiety acting as a radical inhibitor.
