Abstract

The thermolysis of (CH3)4N+Br(OCF3)2- between −70 and −10 °C, evolving F2CO during the decomposition, gave (CH3)4N+BrF2-. The characterization of (CH3)4N+BrF2- was carried out by IR, Raman, and 19F- and 13C-NMR. For BrF2- two infrared absorption bands at 236 and 450 cm-1 and one band in the Raman spectrum at 460 cm-1 were observed in accord with a centrosymmetric structure. Ab initio calculations are presented for BrF2- the isoelectronic KrF2, and other related compounds with D∞h symmetry.
