Selective ring expansion and C-H functionalization of azulenes.
Park S, Kim CE, Jeong J, Ryu H, Maeng C, Kim D, Baik MH, Lee PH. Park S, et al. Nat Commun. 2023 Dec 1;14(1):7936. doi: 10.1038/s41467-023-43200-7. Nat Commun. 2023. PMID: 38040685 Free PMC article.
This result is notable for extending the Buchner reaction, previously limited to benzenoid aromatics, to nonbenzenoid compounds. The chemoselectivity of the reaction can be directed towards C-H functionalization by substituting the Cu catalyst with AgOTf. ...Further …
