The authors apologise that in the above article all of the conversions and yields for the Negishi cross-coupling reactions are the same in Tables 1-4. The corrected tables with correct conversions and yields are displayed below.

Table 1 Negishi cross-coupling reactions of aryl bromides with diphenylzinc catalyzed by 1^a

^aReaction conditions: 2.0 mmol aryl halide, 1.4 mmol diphenylzinc, 4 ml NMP, catalyst (0.01 mol%) added in solution (dioxane), reaction performed at 100°C. Conversions determined by GC/MS, based on aryl halide. ^b2.8 mmol of diphenylzinc was used.
