Iron‐Photocatalyzed Alkene Chloroaminoxylation: A Platform for Orthogonally Activatable Building Blocks

Angewandte Chemie, EarlyView.
An iron‐photocatalyzed unsymmetrical 1,2‐hetero(atom)difunctionalization of alkenes enables to install orthogonal C–Cl and C–O (alkoxyamine) handles which provides access to diverse nucleophiles via complementary reactivity (SN and photoredox) at two distinct sites. Detailed mechanistic studies elucidate interesting features of the iron catalytic cycle.
