Abstract

Proton-transfer reactions involving the silaformyl anion, HSiO-, and its conjugate acids, HSiOH and H2SiO, have been investigated with ab initio methods. Calculations through fourth-order perturbation theory suggest possible routes for proton transfer. Accurate estimates for the acidity of H2SiO and HSiOH are presented and discussed in light of earlier experimental estimates.
