Page 12035 and Supporting Information pp S91−S94. It has
come to our attention that the wrong initial concentration of
1a was erroneously used in two experiments of the “same
excess” protocol.1 The experiments were thus repeated (0.055
rather than 0.06 mol/L of 1a was erroneously used before),
and an excellent overlay of the “time-adjusted same excess”
reaction profiles and the standard reaction profile, as previously
presented, was found. This indicates that no significant catalyst
deactivation takes place and that the active catalyst
concentration remains constant during the catalytic reaction.
The conclusions are thus not affected by the unintentional
error. The corrected Figure 1 is shown below, and a corrected
including Figures S1−S28 and Tables S1−S8 (cor-
rected) (PDF)
