An unprecedented gas-phase condensation reaction mediated by a bissilylated chloronium ion intermediate

Gas-phase Cl 2 Si(OH) + and Si 2 OCl 4− n (OH) n +1 + ( n = 0-4) ions are shown to undergo a novel condensation reaction with SiCl 4 that provides a potentially useful pathway for a variety of networks containing the -(Si-O-Si)- backbone. Theoretical calculations reveal that these reactions proceed...

Description
Summary:Gas-phase Cl 2 Si(OH) + and Si 2 OCl 4− n (OH) n +1 + ( n = 0-4) ions are shown to undergo a novel condensation reaction with SiCl 4 that provides a potentially useful pathway for a variety of networks containing the -(Si-O-Si)- backbone. Theoretical calculations reveal that these reactions proceed via a bissilylated chloronium ion intermediate. Gas phase Cl 2 Si(OH) + ions undergo an unusual condensation reaction with SiCl 4 to yield Cl 3 SiOSiCl 2 + ions that by progressive hydrolysis or solvolysis give rise to a large variety of siloxane type moieties.
