Abstract
Correction for ‘Nickel-catalyzed reductive coupling of alkyl halides with other electrophiles: concept and mechanistic considerations’ by Jun Gu et al., Org. Chem. Front., 2015, 2, 1411–1421.
On page 1416, due to an incorrect conclusion being drawn regarding the rate-determining steps, the authors regret that the following sentence in the original text:
Therein the reductive elimination becomes rate-determining with an energy barrier of ∼10 kcal mol−1. Given the small energy difference between the possible mechanisms, subtle changes of the reaction parameters (e.g. concentrations) may favor one of the reaction pathways.
Should be corrected to:
Therein the rate-determining steps may arise from oxidative addition of aryl halides to the low valent Ni complexes (∼9–18 kcal mol−1 of energy barriers). The energy barriers for the reductive elimination steps were ∼10 kcal mol−1. Calculations using the UB3LYP/LANL2DZ method generated a small energy difference (14.7 vs 15.7 kcal mol-1) in the rate-determining steps between the two possible mechanisms. Subtle changes of the reaction parameters (e.g. concentrations) may favor one of the reaction pathways.
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
