    • note
    • Macrocycle 8a (R = H, n = 0) was detected by LRMS as well as HRMS, but other spectral data could not be measured because of low solubility in any organic solvents after evaporation. The macrocyclic structure of 8c was determined by X-ray crystal structure analysis. See the Supporting Information.

    • The reductive aromatization of 5a, 6a, and 7a (n = 0) did not proceed to give the corresponding cyclynes at all.

    • Bertozzi et al. also mentioned that the reductive aromatization of cyclohexadiene moieties to synthesize cycloparaphenylenes led to a complex mixture. See ref 5.

    • The reductive aromatization of 8b also gave the corresponding cyclyne, but the cyclyne gradually decomposed under the reaction conditions. See the Supporting Information.

    • The time-dependent (TD) calculation of the model cyclyne shown in Figure 2 indicates that the UV-vis absorption spectrum of 11 is reasonable. The results of calculation are summarized in the Supporting Information.
