| Abstract: | Five-coodinate potassium hydridosilicates, [HSi(OR)4]− K+ (R Et, i-Pr, Ph), have been obtained in good yield from the reaction of a trialkoxy- or triarylox-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. |
