Multicomponent Oxyalkylation of Styrenes Enabled by Hydrogen‐Bond‐Assisted Photoinduced Electron Transfer

Herein, we disclose a strategy for the activation of N-(acyloxy)phthalimides towards photoinduced electron transfer through hydrogen bonding. This activation mode enables efficient access to C(sp³ )-centered radicals upon decarboxylation from bench-stable and readily available substrates. Moreover, we demonstrate that the formed alkyl radicals can be successfully employed in a novel redox-neutral method for constructing sp³ -sp³ bonds across styrene moieties that gives straightforward access to complex alcohol and ether scaffolds.
