The authors wish to point out that the following references include errors in the listed authors and author orders: Ref. , Ref. , Ref. , Ref. , Ref. , Ref. , Ref. , and Ref. . The citation manager software employed, Mendeley, sporadically generates erroneous citations from Portable Document Format (PDF) files in lieu of proper citations associated with the PDFs’ linked Research Information Systems (RIS) files. The authors wish to state that there is a mistake in Figure 3. The acetone product in the HNL mechanism is missing its oxygen atom. The correct figure follows on the next page.
