A general route to five-coordinate hydridosilicates

Article abstract of DOI:10.1016/0022-328X(89)85437-3

Five-coordinate potassium hydridosilicates, ^- K⁺ (R=Et, i-Pr, Ph), have been obtained in good yield from the reaction of a trialkoxy- or triaryloxy-silane with the corresponding potassium alkoxide or aryloxide, and characterized spectroscopically.Reaction of the hydrosilicates with an excess of Grignard reagent gives the corresponding triorganosilanes.
