Popis:	Octahydrotriborate salts, B3H8 −, have been prepared by the reaction of NaBH4 with Lewis acids such as BX3·BDMA (BDMA = benzyldimethylamine, × = Cl,Br) or C2H5I in diglyme. The presence of BH3·BDMA as a by-product in the former reaction provides new insight into the reaction mechanism of B11H14 − formation. In acetonitrile-water solutions of HCl or CH3CO2H, the B3H8 − anion reacted to give B3H7CH3CN or B3H7CH3CO2 − characterized by 11B NMR spectroscopy. Their kinetic hydrolysis study was consistent with NMR analysis. Reaction of Bu4NB3H8 and CuCl2 at 0°C produced pure B3H6Cl2 −. An AM1 theoretical study of the substituted derivatives B3H7L (L = Cl−, CH3CN, CH3CO2 −, OH−) and B3H6L2 (L = Cl−) is reported.
