THE RELATIVE ACCEPTOR POWER OF BORON TRIHALIDES TOWARD ACETONITRILE BY PROTON NUCLEAR MAGNETIC RESONANCE MEASUREMENTSProton nuclear magnetic resonance spectra of BF3, BCl3, and BBr3 adducts of acetonitrile have been measured in nitrobenzene solution. Single peaks were observed in each case and chemical ...
作者: S Jassim 摘要: AM1 Molecular Modeling has been used in the comparison of Lewis acid strength of Boron Trihalide using available opportunities in this method such as HOMO-LUMO gap , infrared frequencies and molecular geometry. HOMO-LUMO separation was employed to evaluate acid strength of ...
SCF-MS-Xα molecular-orbital calculations have been carried out on the boron trihalides BX3(X = F, Cl, Br, I) in order to investigate the bonding and nuclear quadrupole coupling in these molecules. Reasonable agreement (to within 30%) is obtained between the calculated and observed halogen ...
