An efficient catalytic synthesis and characterization of new styryl-ferrocenes and their trans-π-conjugated organosilicon materials

A selective and efficient catalytic method was developed for the synthesis of new styryl-conjugated silyl-ferrocene materials. The use of an effective palladium catalytic system [Pd(η²-dba)(P(o-tolyl)₃)₂] (3) with a K₃PO₄ base solution allowed us to obtain new, reactive ferrocene olefins which can be used in various applications. In addition, using the stereo-control silylative coupling reaction we received unique new organosilicon trans-vinylene products with a built-in metallocene.
