Abstract
The first four isomers of C~70~(nโC~3~F~7~)~8~ synthesized by the ampoule reaction of C~70~ with nโC~3~F~7~I, isolated by HPLC, and characterized by Xโray crystallography possess unprecedented addition patterns among C~70~X~8~ compounds.

## Abstract Reaction of C~70~ with ten equivalents of silver(I) trifluoroacetate at 320โ340โยฐC followed by fractional sublimation at 420โ540โยฐC and HPLC processing led to the isolation of a single abundant isomer of C~70~(CF~3~)~__n__~ for __n__ = 2, 4, 6, and 10, and two abundant isomers of C~70~(
bond lengths are 1.109(2) and 1.103(5) , respectively, which are among the shortest observed to date. Tris(pentafluoroethyl)borane carbonyl and (C 3 F 7 ) 3 BCO slowly decompose at room temperature to yield CO, difluoroperfluoroalkylboranes and perfluoroalkenes. The decomposition of (C 2 F 5 ) 3 BCO
