Correction to: Nature Synthesis https://doi.org/10.1038/s44160-021-00002-3, published online 12 January 2022.

In the version of this article initially published, there were label errors in Fig. 8b–d. In Fig. 8b, right-hand, lower side of the reaction, “r.t.” (room temperature) should have appeared in place of “TBM.” In Fig. 8c,d, lower-left sides, “r.t.” should have appeared in place of “TBM.” These changes have been made in the HTML and PDF versions of the article.
