THE RELATIVE ACCEPTOR POWER OF BORON TRIHALIDES AND BORANE TOWARD TRIMETHYLAMINE

Abstract
Gas phase displacement reactions of boron trihalides from their trimethylamine adducts show that the order of acceptor power is: BBr3 > BCl3 > BF3 > 1/2(B2H6). This order agrees with recent theoretical calculations and dipole moment, calorimetric, and infrared measurements on boron trihalide complexes with other reference bases.
