Usage

General Description

1,3-Bis(trichlorosilyl)propane is a type of organosilicon compound, chemical formula C3H8Cl6Si2, which belongs to the class of organochlorosilanes. It has six chlorine atoms and two silicon atoms attached to a three-carbon propane backbone. As such, it is commonly used in the production of silicones, where its chlorides form bonds with oxides or hydroxides. It is colorless, relatively stable, and the presence of Cl makes them more reactive. In laboratory settings and in industry, these compounds are generally handled with caution due to their propensity to hydrolyze, causing potential harm to humans and the environment.

Synthesis of a Counteranion-Stabilized Bis(silylium) Ion

The preparation of a molecule with two alkyl-tethered silylium-ion sites from the corresponding bis(hydrosilanes) by two-fold hydride abstraction is reported. The length of the conformationally flexible alkyl bridge is crucial as otherwise the hydride abstraction stops at the stage of a cyclic bissilylated hydronium ion. With an ethylene tether, the open form of the hydronium-ion intermediate is energetically accessible and engages in another hydride abstraction. The resulting bis(silylium) ion has been NMR spectroscopically and structurally characterized. Related systems based on rigid naphthalen-n,m-diyl platforms can only be converted into the dications when the positively charged silylium-ion units are remote from each other (1,8 versus 1,5 and 2,6).

Process for Preparing Polysilylalkane

Polysilylalkane according to the present invention is represented by following formula. The present invention has an advantage that bis(silyl)alkanes or tri(silyl)alkanes can be manufactured in a high yield by dehydrochlorination with a small amount of catalyst by using a silane compound having a dichloro organic matter or a dichloromethyl group.COPYRIGHT KIPO 2020
