Abstract

Page 1661 and Supporting Information. The 11 B NMR chemical shift of compound 8 was reported incorrectly. The genuine 11 B NMR signal for 8 is a broad singlet at δ -6.7 ppm instead of δ 0.3 ppm at room temperature. The 11 B NMR chemical shift and resolution of the scalar 11 B- 1 H coupling are temperature dependent. As expected, a doublet resonance signal at δ -8.4 ppm with 1 J H-B = 80 Hz could be observed in the 1 H-coupled 11 B NMR spectrum at -80°C. Correspondingly, the same coupling could be resolved as a 1:1:1:1 quartet in the 1H NMR spectrum at -80°C and confirmed by a 1 H, 11 B-HMQC NMR experiment. For the D 2 cleavage product 8-d 2 , the broadened singlet of the DBPh 3 anion appears at δ -7.8 ppm in the 11 B NMR spectrum at room temperature. The corrected NMR spectra of compound 8 are provided as Figures S18a,b, S19, and S23a-d in the revised Supporting Information (Experimental Section). These corrections do not affect the conclusion of the Article.
