《A lutidine-promoted photoredox catalytic atom-transfer radical cyclization reaction for the synthesis of 4-bromo-3,3-dialkyl-octahydro-indol-2-ones》 was written by Zhao, Quan-Sheng; Xu, Guo-Qiang; Xu, Ji-Tao; Wang, Zhu-Yin; Xu, Peng-Fei. Name: fac-Tris(2-phenylpyridine)iridium And the article was included in Chemical Communications (Cambridge, United Kingdom) in 2020. The article conveys some information:
Reported herein is a visible-light-catalyzed photoredox atom-transfer radical cyclization (ATRC) halo-alkylation of 1,6-dienes with α-halo-ketones as the ATRC reagent. This process exhibits high atom economy, high step economy, and high redox economy, which can directly construct a 4-bromo-3,3-dialkyl-octahydro-indol-2-one I (R1 = C6H5, 4-FC6H4, Ts, etc.; n = 0,1) core under mild conditions in one pot, and lutidine is found to be the key promoter for this ATRC process. In the part of experimental materials, we found many familiar compounds, such as fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6Name: fac-Tris(2-phenylpyridine)iridium)
fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6) belongs to pyridine. Pyridines form stable salts with strong acids. Pyridine itself is often used to neutralize acid formed in a reaction and as a basic solvent. Name: fac-Tris(2-phenylpyridine)iridium
