The competitive reaction of C4F9CF=CFBF2 (cis : trans = 1.2:1) with XeF2 demonstrated for the first time a remarkably lower reaction rate of the trans isomer with respect to the cis isomer in the xenodeborylation reaction (formation of the [C4F9CF=CFXe]+ cation with a cis : trans ratio of 2.5 to 4:1) and allowed us to develop reaction conditions for the syntheses of [trans-C4F9CF=CFXe]+ salts.
