And the article was published in Advanced Synthesis & Catalysis in 2019. Safety of fac-Tris(2-phenylpyridine)iridium The author mentioned the following in the article:
Radical cyclization/fluoroalkylation of enyne I with BrCF2CO2Et in presence of K2CO3 in MeCN at 120° under air using CuI and Me4Phen as catalyst afforded (E)-indenone II (68%) whereas the same substrates under visible light photocatalytic conditions with fac-Ir(ppy)3 in presence of Et3N in THF under N2 at room temperature afforded (Z)-III (59%). In the part of experimental materials, we found many familiar compounds, such as fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6Safety of fac-Tris(2-phenylpyridine)iridium)
fac-Tris(2-phenylpyridine)iridium(cas: 94928-86-6) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. Safety of fac-Tris(2-phenylpyridine)iridium
