    • Notably, no reaction occurred under our milder reaction conditions using tetrabutylammonium bromide or chloride instead of tetrabutylammonium iodide as a pre-catalyst. For comparisons of our "iodine"-catalyzed oxidations with their "bromine"-catalyzed oxidations, see the Supporting Information. We previously reported our preliminary results

    • The reaction of 9 under identical reaction conditions of Scheme 4 gave 10, but only in ≤% yield. Shim etâal. reported that 10 was obtained from a similar substrate (1,1-diphenyl-2-vinylcyclopropane) under photooxidation conditions, see:,. Thus, 10 might be produced from 8 and/or 9 under the reaction conditions shown in Scheme 4.
