Correction for Shin et al., Cathodic electroorganic reaction on silicon oxide dielectric electrode

CHEMISTRY Correction for “Cathodic electroorganic reaction on silicon oxide dielectric electrode,” by Samuel J. Shin, Sangmee Park, Jin-Young Lee, Jae Gyeong Lee, Jeongse Yun, Dae-Woong Hwang, and Taek Dong Chung, which was first published December 14, 2020; 10.1073/pnas.2005122117 (Proc. Natl. Acad. Sci. U.S.A. 117, 32939–32946).

The authors note that on page 32943, left column, Eqs. 1–4 should instead appear as

$${\text{H}}^{+}+{\text{e}}^{-} \underset{}{\overset{}{\rightleftharpoons }}\text{H}\cdot \hspace{0.17em}\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}\hspace{0.17em}{E}_{H\cdot }^{o’}=-2.30\hspace{0.17em}\text{V}$$ [1]

$$\text{H}\cdot +\text{H}\cdot \underset{}{\overset{}{\rightleftharpoons }}{\text{H}}_{2}K=\frac{\left[H_2\right]}{{[H\cdot ]}^2}$$ [2]

$$2{\text{H}}^{+}+2{\text{e}}^{-}\underset{}{\overset{}{\rightleftharpoons }}{\text{H}}_2{E}_{H_2}^{o’}=0.000\hspace{0.17em}\text{V}$$ [3]

$$\mathrm{\Delta }G=-2FE=-2F{E}_{H_2}^{o’}-\mathit{RTln}\frac{{\left[H^{+}\right]}^2}{\left[H_2\right]}=-2F{E}_{H\cdot }^{o’}-\mathit{RTlnK}-\mathit{RTln}\frac{{\left[H^{+}\right]}^2}{\left[H_2\right]}$$ [4]

Additionally, in line 4 of the second column in page 32943, the BDE was underestimated. This should instead appear as “This is comparable to the homolytic bond dissociation energy (BDE) of C-H in the 9-, 10-site of 1a, 448 ∼ 464 kJ/mol”.

The online version has been corrected.
