摘要：

Reaction of 2-bromo-1-decenyl iodonium salt with bromide ion in acetonitrile results in nucleophilic substitution with complete retention. Observed rate constants show unexpected dependence on the bromide concentration, conforming with a mechanism involving ligand coupling within a bromoiodane 10-I-3 intermediate.
