Abstract: Fluorinated bis‐ and tris(pyrazolyl)boratocopper complexes catalyze the nitrene insertion to C−H bonds of aromatic hydrocarbons efficiently producing amination products in good to excellent yields at room temperature. Imidoiodanes, PhI=NTs (Ts=p‐toluenesulfonyl) and PhI=NNs (Ns=p‐nitrophenylsulfonyl) serve as… read more here.

DOI: 10.1134/s1070363219050165
Abstract: Claisen condensation of diacetylated fused aromatic and heteroaromatic compounds (fluorene, dibenzofuran, dibenzothiophene, or carbazole) with polyfluorocarboxylic acids esters in the presence of bases has afforded the ligands containing two β-diketonate groups. Their complexation with Eu3+… read more here.
