In 2019,Organic Letters included an article by Cheng, Yuan-Yuan; Lei, Tao; Su, Longlong; Fan, Xiuwei; Chen, Bin; Tung, Chen-Ho; Wu, Li-Zhu. Safety of fac-Tris(2-phenylpyridine)iridium. The article was titled 《Visible Light Irradiation of Acyl Oxime Esters and Styrenes Efficiently Constructs β-Carbonyl Imides by a Scission and Four-Component Reassembly Process》. The information in the text is summarized as follows:
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, e.g., I showing good functional group tolerance and high atom economy. Control experiments as well as spectroscopic and electrochem. studies revealed the efficient intermol. reorganization of oxime ester into styrene with the aid of solvent exchange.
