Potassium boron hydride

PORONCOMPOUNDS - BORON HYDRIDES, HETEROBORANES AND THEIRFffiTALLADERIVATIVES] (Vol 4) Potassium dibismuthide [12431-17-3]... [Pg.802]

A noteworthy development is the use of KH for complexing alkylboranes and alkoxyboranes to form various boron hydrides used as reducing agents in the pharmaceutical industry. Potassium tri-j -butylborohydride [54575-50-7] KB(CH(CH2)C2H )2H, and potassium trisiamylborohydride [67966-25-0] KB(CH(CH2)CH(CH2)2)3H, are usefiil for the stereoselective reduction of ketones (66) and for the conjugate reduction and alkylation of a,P-unsaturated ketones (67). [Pg.519]

Complex aluminum and boron hydrides can contain other cations. The following compounds are prepared by metathetical reactions of lithium aluminum hydride or sodium borohydride with the appropriate salts of other metals sodium aluminum hydride [55], magnesium aluminum hydride [59], lithium borohydride [90], potassium borohydride [9i], calcium borohydride [92] and tetrabutylammonium borohydride [95]. [Pg.14]

Electrolytic reduction and thermal decomposition have not yet been apphed in large scale commercial methods. Electrolysis of alkali or alkaline earth borates produces boron in low purity. Electrolytic reduction of fused melts of boron trioxide or potassium tetrafluroborate in potassium chloride yield boron in high purity. Also, boron tribromide or boron hydrides may be thermally dissociated hy heating at elevated temperatures. [Pg.123]

Sodium hypoborate, NaH3BO.—On cooling the mixture produced by the interaction of a very concentrated solution of potassium hydroxide and boron hydride, B4H10, the very deliquescent sodium hypoborate is obtained.1... [Pg.149]
