    • The experiment in Equation (4) also demonstrates that C-H functionalization of the 4-nitrophenyl ring of 1 g is irreversible in the presence of 2 a. Exposure of 1 g to the conditions shown in Equation (4) but in the absence of 2 a led to partial deuterium incorporation (28 % D) at the ortho-positions of the 4-nitrophenyl ring, showing that C-H functionalization of 1 g is reversible when the 1,3-enyne is not present. See the Supporting Information for details.
