✦ Synopsis

The reaction of iodobistrifluororncthylphorphine. P(CF3)21, with atomic fluorine was studied by fast-flow ESK methods. The initial stage of the reaction is the abstraction of I by F. to form IT with a bimolecular rdtc constant of (1 .O +-0.3) X 1014 cm3 mol-t s-t at 297 K. In the prescncc of excess 1:. stcpwise addition to the phosphorous occurs. In the presence of excess P(CF3)2I. the reaction P(CF3)z + IF -P(CF3)3 1' + 1 appears to take place. This reactlon rate is slow relative to P(CF& + F -P(CF:J)* I:.
