(a) A reviewer has offered a reasonable alternative explanation. The rationale posits that a reversible cyclization of 24 would lead to an unstabilized oxygen-centered radical that would quickly revert to 24. In contrast, both the cyclization of 27 and 29 would afford a stabilized radical. Perhaps, as the reviewer suggested, stabilization increases the lifetime of the intermediate enough to allow formation of the second σ-bond to occur.

(b) Monoradicals and TMM diyls differ in several important ways. In particular, the latter can exist in more than one spin state (singlet/triplet) whose geometries (planar/bisected) and chemistries often differ, and second, because they are diradicals, there are two possible sites to which atom transfer can occur. That a 1,7-hydrogen transfer is not observed despite the fact that the transition state for it is calculated to reside only 1 kcal/mol above that for the 1,5 transfer is consistent with the notion that such a process is slowed entropically by the necessity to form an eight-membered ring in the transition structure leading to transfer.
