Abstract:
Bromoalkanes are key structural motifs in bioactive molecules and synthetic intermediates. While atom transfer radical addition (ATRA) reactions using brominated alkanes, such as CBr4 and CHBr3, enable efficient synthesis of polybrominated alkanes from alkenes, strategies for divergent synthesis of various polybromoalkanes are underexplored. Herein, we report a visible-light-induced Fe-catalyzed atom transfer radical addition (ATRA)-reductive debromination cascade between alkenes and CBr4, switchably affording 1,1,1,3-tetrabromoalkanes, 1,1,3-tribromoalkanes, or 1,3-dibromoalkanes by simply modulating reaction conditions. This strategy offers a versatile and efficient platform for the divergent synthesis of polybromoalkanes from readily available starting materials.

Consider the bromination of cyclopentene. Molecular bromine is polarized in the proximity of the π electrons of cyclopentene. An electrophilic bromine atom adds across the double bond, forming a cyclic bromonium ion intermediate.
