Lee, S. J.; Terrazas, M. S.; Pippel, D. J. J. Am. Chem. Soc. 2003, 125, 7307, and references cited therein for other cases using the endocyclic restriction test. The data from double-labeling experiments provide definitive distinctions between intermolecular and intramolecular pathways for these sulfur transfers. Assignments for the favored geometries for atom-transfer reactions under this test are conclusive and independent of yields. Low yields of the atom-transferred products or the operation of pathways which give other products do not compromise the test under this protocol.

n had tended to rearrange prior to mixing with 8. Careful purification of each component and analysis was carried out to show this did not occur prior to the reaction. The fact that there was not scrambling of the labels in the conversion of 7 to 9 under the same conditions establishes that label scrambling prior to phenyl sulfonyl transfer is not occurring in this case.

Our efforts to investigate a long-chain tether for sulfur(II) by the investigation of i were not successful (Jarboe, S. Ph.D. Thesis, University of Illinois, 2002, Absent the experimental results for that case, it could be argued that there is insufficient dilution in these experiments for a definitive conclusion. Our preference, consistent with previous work, is to favor a linear transition structure.8a Chemical Equation Presented
