Org. Chem. Front., 2024, 11,2241-2248
DOI: 10.1039/D4QO00136B, Research Article
Xinyu Wang, Zhaobin Wang
We present an approach involving Fe-catalyzed B–H and Si–H insertion of gem-dichloroalkanes. In contrast to previous strategies, our method uses gem-dihaloalkanes as non-stabilized carbene precursors and operates through a radical reaction pathway.
