Iridium-Catalyzed Enantioselective Allylic Substitution with Aqueous Solutions of Nucleophiles
, 2019 The iridium-catalyzed asymmetric allylic substitution under biphasic conditions is reported. This approach allows the use of various unstable and/or volatile nucleophiles including hydrazines, methylamine, t-butyl hydroperoxide, N-hydroxylamine, α ...

Journal of the American Chemical Society, 2008 This work reports the synthesis and full characterization of 5,10,15-tris-pentafluorophenylcorrolato-iridium(III) bis-trimethylamine 1 and its octabromo derivative 2. The corrole is planar in both cases (the mean deviation from the plane is as low as 0.0371 A for 1 and 0.0325 A for 2), the UV-vis spectra display a split Soret band with a shoulder ...
