摘要：

Xenon difluoride reacted with alkynylborate salts, K[RFC CBF3], in anhydrous HF (aHF) to give alkynylxenonium salts, [RFC CXe][BF4] (R-F = CF3, C3F7, (CF3)(2)CF), in 50-55% yield. Both [FXe][SbF6] and K[C3F7C CBF3] formed the [C3F7C CXe](+) salt in aHF. In the reaction of XeF2 with the alkenylborate salt, K[CF2=C(CF3)BF3], the competitive hydrodeboration reaction (formation of CF2=C(CF3)H in 85% yield) exceeded the xenodeboration reaction (formation of the xenonium salt [CF2=C(CF3)Xe][BF4] in 15% yield only). K[4-BF3C5F4N] did not react with XeF2 in aHF, but underwent fluorine addition in the presence of AsF5. (C) 2012 Elsevier B.V. All rights reserved.
