What is the (e.g., multiple-choice, free-response mechanisms, or synthesis design)?

: Instead of a simple methyl shift, the ring carbon migrates to contract the six-membered ring into a highly stable cyclopentane ring, driven by the simultaneous formation of a carbon-oxygen double bond (oxocarbenium ion). She added a footnote: “The expected SNAr product

But the twist? She added a footnote: “The expected SNAr product is not formed. Propose an alternative mechanism involving single-electron transfer, and justify with DFT data from a 2021 Chem. Sci. article.”
