The diborane(4) derivatives Mes,BB(Mes)Ph and Me,N(Ph)BB(Ph)NMe, readily react with lithium powder in ether to give the doubly reduced salts [{(Et,O)Li},Mes,,BB(Mes)Ph] and [{(EtzO)Li}~Me,N(Ph)BB(Ph)NMe~]. Both species, which were isolated as red crystals, have been characterized by X-ray crystallog

Two methods have been employed to prepare boron-doped carbon materials. One method utilized ion implantation to dope the surface region of vitreous carbon with up to 12 atomic % boron. The other method used CVD to prepare -1-2 micron thick carbon coatings with various boron contents (0 to 15 atomic
Nanocrystalline boron nitride (BN) with a whisker-like morphology has been synthesized from the reaction of KBH 4 and NH 4 Cl at a temperature of 6503C and a pressure of about 22 MPa. The pressure is much lower than that of previous routes and the yield of nanocrystalline BN reached 70%. X-ray powde
