Synthesis and characterization of variously asymmetrically chloro-substituted disilanes and trisilanes – A new perspective on known compounds

摘要: Abstract Asymmetrically phenyl-substituted disilanes of the general formula RMe 2 Si–SiMePh ( MPD02 : R = Me, MPD12 R = Ph) and trisilane (PhMe Si) SiMePh MPT111 ) were prepared from corresponding monosilanes using lithium as coupling reagent. These compounds utilized precursors for preparation chlorosilanes Cl MeSi–SiMe R CMD20 R = Me; CMD21 R = Cl) (ClMe SiMeCl CMT111 ). The phenyl groups selectively removed acetyl chloride anhydrous AlCl 3 . Subjecting these methyloligosilanes to redesigned literature-known reaction conditions, strengths synthetic routes shown so far combined. In addition, not only methyl-substituents are applicable, since we used Ph t Bu)Si–SiMe BuMPD21 precursor BuCMD21 characterization phenyl- chloro-substituted di- trisilanes mentioned above is completely reported in literature. They fully analyzed by means NMR IR spectroscopy, GC–MS, DSC elemental analysis at our chair. studies synthesized led assumption a plastic crystalline behavior certain compounds. Beyond that, CV measurements pointed out that their reduction occurs highly negative potentials.
