Visible Light Irradiation of Acyl Oxime Esters and Styrenes Efficiently Constructs β-Carbonyl Imides by a Scission and Four-Component Reassembly Process
Acyl 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
