Styrenes serve as versatile building blocks, and the 1,2-difunctionalization reaction is a pivotal method for increasing molecular complexity by adding two new functional groups across the C=C bond. In 2024, Ngai and coworkers reported a novel approach for the regioconvergent synthesis of β-acyloxyethylarenes, which involves the bromo-acyloxylation of styrenes followed by bromo/acyloxyl transposition (BrAcT) and selective radical ketonylation catalyzed by excited-state Cu(I)-BINAP (Figure ). The method was successfully applied to a diverse range of bromo-acyloxylated styrenes, including derivatives of complex molecules, yielding the desired products in good to excellent yields (Figure ). Notably, a "one-pot" procedure that starts directly from styrenes, bypassing the isolation of the "bromo-acyloxylated" intermediate, afforded the desired products in comparable yields, showcasing the synthetic utility of this method.
