  Borane-functionalized oxide supports: development of active supported metallocene catalysts at low aluminoxane loading

  摘要：

  Treatment of hydroxylated silica or alumina with tris(perfluorophenyl)borane (1), bis(perfluorophenyl)borane (2) or bis(perfluorophenyl)boron chloride (3), provides borane-functionalized supports of variable composition, as revealed by in situ monitoring by F-19 NMR spectroscopy and/or elemental analysis. These chemically treated supports can be impregnated with Cp2ZrMe2 to provide supported catalysts for ethylene polymerization. Although some of these supported catalysts are active for ethylene polymerization in the presence of alkylaluminum compounds (e.g., TMA, TIBAL), all of these catalysts are more efficiently activated in the presence of small quantities of methyl aluminoxane, even at very low Al:Zr ratios of 10:1. The polymer properties are quite similar to those produced using the soluble catalyst Cp2ZrMe2/B(C6F5)(3), again in the presence of MAO at low loading. A variety of experiments suggest that minimal leaching of the metallocene complex from the support occurs under the conditions studied; in particular, production of polyethylene with high bulk densities (> 0.2 g/cm(3)) and little reactor fouling, even at elevated temperature in toluene slurry, is observed.

  The search for H2BOH: a matrix isolation study

  摘要：

  Merged jet copyrolysis of samples of Ar/B2H6 with either Ar/H2O or Ar/O2 followed by trapping into an argon matrix has led to the formation and isolation of the known species boroxin, H3B3O3. These results differ from the gas phase microwave study of this system, where H2BOH was identified and characterized. Local density functional calculations of the vibrational spectrum of this compound were carried out to aid in the search for absorptions of H2BOH, and are reported. The difference between the microwave study and the present study persisted despite very similar reaction conditions. Possible origins of this discrepancy are discussed.

  The microwave spectrum of BH2OH, a transient intermediate in the reaction between diborane and water, has been detected and analyzed. This molecule has also been found in the reaction between diborane and oxygen. The lifetime of BH2OH in a copper waveguide cell is a few seconds, which is much shorter than that of BH(OH)2. The rotational and centrifugal distortion constants have been determined for the 11BH2OH, 10BH2OH, 11BD2OD, and 11BH2 18OH species. From the rotational constants the molecular structure has been determined as r(B–O) = 1.352(4) Å, r(O–H) = 0.967(14) Å, &BOH = 112.0(17)°, &HcBO = 121.8(8)°, and &HtBO = 117.2(8)°, the r(B–H) = 1.200 Å being assumed. For the normal species, the dipole moments have been determined as μa = 0.497(7)D, μb = 1.423(15)D, and μtotal = 1.506 D. The quadrupole coupling constants have also been determined.
