In Table 1 of the original paper, the structures 3o, 3p and 3q are incorrect. Upon further NMR investigation, the correct structures are shown below. The specific mechanistic details by which these compounds are converted to products 4o–4q are currently under investigation. The authors apologize for the mistake and any confusion it may have caused.

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
