title: Synthesis of novel styryl-N-isopropyl-9H-carbazoles for designing trans-conjugated regular silicon hybrid materials.
abstract: 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.
