✦ Synopsis

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 was found to follow a first-order rate law with E a = 107 kJ mol À1 .

The reactions between F2 and the lowest members of the homologous series of perfluoroalkyl iodides (CF31. C2F51. and n-C3F71) have been studied. For these compounds, an exponential decrease in the alkyl iodide concentration over time following an induction period is observed for certain experimental
