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).

Paragraph 0056-0057; 0084-0086, (2020/04/17)
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
