GAS-PHASE ION CHEMISTRY OF SILOXIDE AND SILAMIDE IONS BY USING THE FLOWING AFTERGLOW - UNUSUAL REARRANGEMENTS INVOLVING SIO AND SIS BOND FORMATION

Abstract

Siloxide ions undergo O/S exchange reactions with suitable sulfur-containing neutrals, e.g. H3SiO-+CS2 ? H3SiS-+COS. Silamide ions similarly undergo NR/O and NR/S exchange reactions together with nucleophilic displacement reactions, e.g. Me3SiNMe + CO2 ? Me3SiO-+MeNCO ? No simple correlation between rate and mechanism is observed for all the studied reactions.
