The authors regret the following errors:
In Scheme 2 the structure of the intermediate (bottom left) is incorrect. A corrected scheme is shown below.
In Table 1, the entry for compound 12b should be deleted as 12b was not prepared; conditions for preparation of 12a' were mistakenly added as entry 12b. A corrected table is shown below.
Throughout the experimental, 2,5-di-tert-butylacenaphtho[1,2-d]pyridazine-7,10-dicarboxamide was referred to as 12b when it should have been referred to as 12a'.
The Royal Society of Chemistry apologises for this error and any consequent inconvenience to authors and readers.
