DOI:10.1002/anie.200903146
日期:2009.9.14
A new coupling partner: Vinylacetate couples with organoboroncompounds in the presence of a rhodium catalyst; carbon–carbon bond formation occurs on the vinylic carbon attached to the acetoxy group. Conventional nickel and palladium catalysts were found to be ineffective for the reaction.

日期:2013.5.3
Intermolecular aminotrifluoromethylation of alkenes catalyzed by [Ru(bpy)3]2+ under visible light irradiation has been explored. The present photocatalytic protocol achieves highlyefficient and regioselectivedifunctionalization of C═Cbonds, leading to a variety of β-trifluoromethylamines. The reaction is applied to “late-stage aminotrifluoromethylation” of steroid and amino acid scaffolds.

日期:2015.8.10
A simple and regiospecific aminohydroxylation of olefins by photoredoxcatalysis has been developed. N‐protected 1‐aminopyridinium salts are the key compounds and serve as amidyl radical precursors by the action of Ir photocatalysts, fac‐[Ir(ppy)3] and [Ir(ppy)2(dtbbpy)](PF6) (ppy=2‐pyridylphenyl, dtbbpy=4,4′‐di‐tert‐butyl‐2,2′‐bipyridine). The present photocatalytic system allows for synthesis of
