radical triggered difunctionalizations of aryl olefins have
been realized using oxime ester as the acyl precursor for the first
time. Irradiation of fac-Ir(ppy)3 and
oxime ester by visible light caused scission into three components,
which recombined with olefins to yield significant β-carbonyl
imides showing good functional group tolerance and high atom economy.
Control experiments as well as spectroscopic and electrochemical studies
revealed the efficient intermolecular reorganization of oxime ester
into styrene with the aid of solvent exchange.
