Organosilicon chalcogenides with trisilane units – bicyclo[3.3.1]nonanes, bicyclo[3.2.2]nonanes and spiro[4.4]nonanes

Different routes for the construction of biologically active diversely functionalized bicyclo[3.3.1]nonanes: an exploration of new perspectives for anticancer chemotherapeutics

“…Both these chalcogenides (355, 356) are found to prefer the twin-boat conformer (Scheme 81). 164 Apart from these sulphur/selenium-containing bicyclo[3.3.1] nonanes, the synthesis of their phosphorus analogues are also well-documented. A unique application of phosphorouscyclization in this regard was demonstrated by Capretta and coworkers.…”

IR laser-induced co-decomposition of gaseous trisilane and carbon disulfide

“…Si-S-Si + H 2 S). Neither of these reactions is known in the gas phase, but reactions leading to silthianes of elemental sulfur with silylene, disilene and polysilanes stabilized with bulky groups have been reported in solution [47]. These major reactions leading to silthianes are accompanied by a polymerization/decomposition of CS fragments into a polymer with low content of the C-S-C bonds.…”

IR laser-induced process for chemical vapor deposition of polyselenocarbosilane films

“…Other minor steps, i.e. reaction of Se 2 with the less stable isomer of silene, methylsilylene and 1,2-dimethylsilene (the dimethylsilylene dimer), as well as insertion of Se into the Si-Si and Si-H bonds, are also feasible [31][32][33][34].…”
