| Abstract: | Several members of the family of (H2O)5CrR2+ complexes have been shown to react cleanly with the interhalogen molecule IBr. Products of reaction are exclusively the organic iodide RI, Cr(H2O)63+, and Br?-; RBr and (H2O)5CrB2+ are not formed. Rates of the IBr reactions are comparable to those of bromine and much higher than those of iodine. These results are consistent with electrophilic reactions and suggest an SE2 mechanism. |
