dc.description.abstractThe preparation of the haloboron cations D2BF2 + and DD'BF 2+, where D=R3N or a pyridine, has been systematically . 19 11 studied uS1ng F and B n.m.r. Both types of amines form numerous difluoroboron cations by heavy halogen displacement from D.BF 2X (X=CI,Br) adducts. Previously, D.BFX2 (X=CI,Br) adducts of aliphatic tertiary amines were unreactive towards cation formation. However, with the more-reactive pyridines, D.BFX 2 adducts formed new monofluoroboron cations D2BFX+ In non-fluorinated D.BX Y3 systems for n -n both pyridines and R3N, haloboron cations of type D2BX2 + and D2BXY+ can be similarly prepared. FAB-MS studies of ionic salts of our haloboron cations resulted in m/z peaks characteristic of D2 BX2 + and its f ragmentation products. These results s upport our n.m.r. solution s t u d ies. Pairwise interaction n . m.r . parameters for tetrahedral boron halide species were def i ned, then used to assist confirmation of our haloboron cations.en_US
