The potential expansion of the variety of catalytic methods for carbon–carbon bond formation is explored in many research centers all over the world. In this work, we describe very precise and controlled catalytic transformations as useful tools for the synthesis of new trans-π-conjugated molecular organic compounds. The combination of Suzuki–Miyaura coupling and cross-metathesis reactions is established as a simple and efficient method for the design of new (E)-stilbenes in the presence of well-defined transition-metal catalysts at 0.0001–1 % loadings. All of the desired products are isolated in good-to-excellent yields (up to 96 % isolated yield) with high purity.

An efficient synthesis and characterization of several new, conjugated styryl-carbazole compounds functionalized by monovinylsilanes in a stereocontrolled approach is presented. All N-organic derivatives were successfully examined in silylative coupling in the presence of ruthenium-hydride complexes 4 and 5. Furthermore, a novel class of vinylene-arylene linear oligomeric materials with 1,4-bis(dimethylvinylsilyl)naphthalene in the main chain was produced. Both reactions proceed very effectively, stereo- and regioselectively, allowing one to obtain E-isomer derivatives with high isolation yields.

Novel trans-stereoregular silylene-carbazolylene-vinylene derivatives (13-15) were synthesized via silylative coupling reaction of 3,6-bis(dimethylvinylsilyl)-N-alkylcarbazole (7-9) catalyzed by ruthenium-hydride complex RuHCl(CO)(PCy3)2 (1). All products were isolated, fully characterized by spectroscopic methods and GPC analyses and their absorption and fluorescence properties were determined.
