C6F5XeF, a versatile starting material in xenon–carbon chemistry

Synthesis, NMR spectroscopic characterisation and reactions of 2,6-difluorophenylxenon fluoride, 2,6-F2C6H3XeF

“…All these findings are supported by quantum-chemical calculations [15] and are in agreement with data published elsewhere [12].…”

“…19 F NMR chemical shifts were detected in the region of those reported for Xe(C 6 F 5 ) 2 [8][9][10] and Xe(2,4,6-F 3 C 6 H 2 ) 2 [12], significantly shifted from those of salt-like fluorophenylxenon derivatives (e.g. [6,12,16,17]). The same can be applied in a somewhat less significant manner with respect to 2,6-difluorophenylxenon compounds.…”

“…In a recent publication [12] Frohn and Theißen proved the existence of 2,4,6-F 3 C 6 H 2 XeC 6 F 5 and Xe(2,4,6-F 3 C 6 H 2 ) 2 by 19 F and 129 Xe NMR spectroscopic means and supported their results by theoretical calculations.…”

“…Cadmium reagents were also employed in the syntheses of 2,4,6-F 3 C 6 H 2 XeC 6 F 5 and Xe(2,4,6-F 3 C 6 H 2 ) 2 [12].…”

“…While ligand exchange reactions with less or low co-ordinating anions have been a major part of investigations [3][4][5][6][7], attempts to prepare hypervalent [10-Xe-2] remained of lower success [8][9][10][11][12].…”
