  The structure of BCl₂: ESR study of an x‐irradiated crystal of BCl₃

  摘要：

  X irradiation of a single crystal of boron trichloride at 77 K yields at least two different radicals. A brief exposure to UV irradiation, however, leaves only one radical whose ESR spectrum shows hyperfine coupling from one boron (10B, 11B) and two equivalent chlorine (35Cl, 37Cl) nuclei and which is identified as BCl2. The g tensor, 11B magnetic hyperfine tensor, 35Cl magnetic and quadrupole hyperfine tensors have been determined and analyzed in terms of the radical’s electronic structure. Problems arising in relating the principal direction of the various tensors to the molecular geometry are discussed. BCl2 is nonlinear with a ClBCl angle of approximately 122° and with the unpaired electron mainly localized on the boron atom.

  The kinetics of the title reactions have been investigated in a high-temperature fast-flow reactor (HTFFR). The observed temperature dependences of the rate coefficients are described, in cm3 molecule−1 s−1, by the expressions: AlCl + HCl (1), k1(T) = 1.1 × 10−11 exp(−13100 K/T) between 1330 and 1610 K, and BCl + HCl (2), k2(T) = 1.2 × 10−10 exp(−12100 K/T) between 1250 and 1620 K. Confidence limits

  已经在高温快速流动反应器（HTFFR）中研究了标题反应的动力学。观测到的速率系数的温度依赖性以cm 3分子-1 s -1的形式表示为：AlCl + HCl（1），k 1（T）= 1.1×10 -11 exp（-13100 K / T）在1330和1610 K之间，以及BCl + HCl（2），k 2（T）= 1.2×10 -10 exp（−12100 K / T）在1250和1620 K之间。
• Studies on BCl and on the exchange reaction of BCl3 with polyboron fluorides

  Gaseous BCl has been prepared at low pressure by reaction of BCl3 with boron at 2000 degreesC or by decomposition of B2Cl4 using either an electric discharge or using flash thermolysis at 1150 degreesC, and then condensed at - 196 degreesC. Reasons are discussed why each method gives BCl capable of generating (Cl2B)(3)BCO when the condensate at - 196 degreesC is treated with CO, but B4Cl4 is only formed from BCl prepared from B2Cl4. The stepwise conversion of (F2B)(3)BCO to (Cl2B)(3)BCO by treatment with BCl3 has been followed by B-11 NMR spectroscopy. Evidence from mass spectrometry and B-11 NMR spectroscopy suggests that reaction of polyboron fluorides, particularly B8F12 and B10F12, with BCl3 yields a new form of B9Cl9 of, as yet, unknown structure which converts slowly to closo-B9Cl9 or closo-B8Cl8 depending on the solvent.
