Hexaborane

Reactions of Boranes with Lewis Bases. Boranes that contain a BH2 moiety, eg, B2H, B H q, hexaborane(12) [28375-94-2] ... [Pg.235]

Besides B,nH,4, the hexaborane(lO) B5H,g also reacts with Me2Zn and Me2Cd... [Pg.50]

Hexaborane(lO) and Fe2(CO)g form /i-[3,4-Fe(CO)4]BftH, . The Fe(CO)4 moiety is coordinated to the unique basal B — B bond of B H,If Os3(00),2 reacts with either closo-(Me3Si)2SnC2B4H4 or nido-(Me3Si)2C2B4H6, the product is closo-... [Pg.95]

In the preparation of 2-(tricarbonylferra)hexaborane(10) by co-pyrolysis of the reactants in a hot-cold Pyrex tube reactor, the latter was severely etched and weakened, sometimes splintering. At 230° a maximum cumulative service life of 4 months was observed, and at 260°C the reactor was replaced at the first signs of etching, usually after 6 runs. [Pg.87]

Isomers of pentaborane and hexaborane derivatives SnPh2(BsHg)2 and Ph3SnB6H9 were studied by H, nB, 13C, and 119Sn NMR spectroscopy in solution and solid state structures of three isomers were also reported.50-53... [Pg.117]

Diaza-OTdo-hexaboranes [N2B4R4R 2] are the products of the fusion of rings NB2R2R. The mechanism of this cluster formation was investigated and in the case of the neopentyl substituent (R = CH2/Bu, R = /Bu) a tetracyclic molecule was identified as a possible intermediate in the ring fusion reaction.81,8111... [Pg.119]

Heating of the dicarba-wtdo-hexaborane(8) 38 at 120 °C leads to elimination of EtBH2 (Scheme 3.2-19) and quantitatively gives pentaethyl-l,5-dicarba-doso-... [Pg.285]

Scheme 3.2-23. Conversion of the 1-carba-orachno-penta-borane(lO) 30 into the 2,4-dicarba-n/do-hexaborane(8) 43, followed by deprotonation yields borate 44. Scheme 3.2-23. Conversion of the 1-carba-orachno-penta-borane(lO) 30 into the 2,4-dicarba-n/do-hexaborane(8) 43, followed by deprotonation yields borate 44.
Many derivatives of isomeric 2,3-dicarba-nido-hexaborane(8) are known, available from the reaction of pentaborane(9) with alkynes [59, 60]. In contrast, the carboranes of type 43 with non-adjacent carbon atoms are rare. [Pg.288]

Derivatives of 2,3,4-tricarba-nido-hexaborane(7) are well known [66], The first derivatives of the 2,3,5-isomer 55 were obtained in a series of 2,3,5-tricarbahexabor-... [Pg.289]
