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.

Five-coordinate potassium dihydridosilicates, K+- (R = Et, i-Pr) have been obtained by reaction of a trialkoxysilane with potassium hydride.Reaction of the dihydridosilicate with an excess of a Grignard reagent gives the corresponding diorganosilane.The ease of reduction of carbonyl compounds by the dihydridosilicate in the absence of a catalyst is indicative of the high reactivity of the Si-H bond in such species.
Hypervalent silicon hydrides: evidence for their intermediacy in the exchange reactions of di- and tri-hydrogenosilanes catalysed by hydrides (NaH, KH and LiAlH4)

Di and tri-hydrogenosilanes, RR'SiH2 and RSiH3 (R=aryl, allyl or benzyl; R'=aryl or alkyl), readily undergo exchange reactions, involving silicon-carbon bonds and silicon-hydrogen bonds, in the presence of hydrides (LiAlH4, KH and NaH) as catalysts.These results are discussed in terms of five-coordinate silicon hydrides as intermediates in the reaction.
