    • Several control experiments were run on the reaction in eq 3. No reaction was observed in the absence of catalyst. Addition of bases to the reaction, to rule out proton involvement, was also investigated. The reaction was run under the same conditions with either 2,6-di-tert-butyl-4-methylpyridine or tris(n-octyl)amine (1 equiv with respect to amine substrate). Neither base had a noticeable effect on the yield or selectivity of the reaction.
