Abstract:
Nitro compounds are important precursors and intermediates for synthesizing pharmaceuticals, agrochemicals, dyes, and explosives, which necessitates the development of novel methods for their synthesis and functionalization. While the spin-paired chemistry of the nitroalkanes has been extensively studied, their radical reactivity is relatively underexplored. Notably, gem-bromonitroalkanes (BNAs) offer a convenient route to electron-deficient α-nitro radicals, which display umpoled electronics, and thus selectivity, compared to majority of the reported radical reactions. This underscores the importance of compiling and analyzing reactions involving this moiety. Therefore, we present our perspective on the free-radical reactivity of BNAs, with a focus on elucidating the mechanistic underpinnings to encourage their wider adoption within the synthetic organic community.

Radical Anti-Markovnikov Addition to Alkenes: Mechanism
The mechanism starts with chain initiation, which involves two steps. In the first chain initiation step, a weak peroxide bond is homolytically cleaved upon mild heating to form two alkoxy radicals. In the second initiation step, a hydrogen atom is abstracted by the alkoxy...
