The same reaction as that
described above for the general amination of hydrocarbons was conducted,
with the exception that a mixture of ethylbenzene and p-X-ethylbenzene (X = MeO, Me, F, I, Br, CF3, NO2) was present (0.125 mmol each). The nitrene source employed was
PhI = NTces (0.50 mmol). The reaction was allowed to run for 5 h and
was then flash chromatographed on silica gel with methylene chloride.
The solvent was then evaporated, and the residue was quantitatively
evaluated by using 1H NMR analysis (CDCl3).
