The pyrolysis of BMe3 has been studied by gas chromatography and mass spectrometry; effects of varying the pyrolysis time and temperature have been investigated. Compounds formed include BMe2Et, Me2BCH2BMe2, carbaboranes Me3B3C2H2, Me5B5C2H2, and 2,4,6,8,9,10-hexamethyl-2,4,6,8,9,10-hexabora-adamantane (Me6B6C4H4). The pyrolysis of BMe3–H2 mixtures, in marked contrast to that of pure BMe3, gives a
已经通过气相色谱和质谱研究了BMe 3的热解。研究了改变热解时间和温度的影响。形成的化合物包括BMe 2 Et,Me 2 BCH 2 BMe 2,甲碳硼烷Me 3 B 3 C 2 H 2,Me 5 B 5 C 2 H 2和2,4,6,8,9,10-六甲基-2, 4,6,8,9,10-六硼烷-金刚烷(Me 6 B 6 C 4 H 4)。BMe 3 -H 2的热解混合物与纯BMe 3的混合物形成鲜明对比,以高总收率(60-66%)得到式Me x H (5 – x) B 5 C 2 H 2(x = 2–5)的甲碳硼烷的混合物。。在D 2,C 2 H 6和HgMe 2的存在下BMe 3的热解提供了甲基参与反应的证据。
