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.

Abstract: Abstract Density functional theory methods have been applied to identify the favoured structural motif of thallium(I) tris(pyrazolyl)methanide complexes. The reaction of [TlN(SiMe3)2]2 with tris(pyrazolyl)methane HC(pz)3 (with pz = pyrazolyl) in toluene furnished the highly air-sensitive title compound… read more here.
