Studies on BCl and on the exchange reaction of BCl3 with polyboron flourides

Gaseous BCl has been prepared at low pressure by reaction of BCl3 with boron at 2000 °C or by decomposition of B2Cl4 using either an electric discharge or using flash thermolysis at 1150 °C, and then condensed at - 196 °C. Reasons are discussed why each method gives BCl capable of generating (Cl2B)3BCO when the condensate at - 196 °C is treated with CO, but B4Cl4 is only formed from BCl prepared from B2Cl4. The stepwise conversion of (F2B)3BCO to (Cl2B)3BCO by treatment with BCl3 has been followed by 11B NMR spectroscopy. Evidence from mass spectrometry and 11B 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.
