DOI: 10.1002/cctc.201901087
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: 10.1002/jhet.2878
Abstract: The bis and tris heterocycles-benzoxazolyl/benzothiazolyl/benzimidazolyl quinazolines linked by sulfur and/or nitrogen were prepared from 2,4-dichloroquinazoline and benzazolyl-2-thiol/benzazolyl-2-amine and studied their antibacterial activity. The nitro-substituted sulfur-linked bisbenzothiazolylquinazoline (12f), bisbenzimidazolylquinazoline (13f), and nitro-substituted sulfur and nitrogen-linked bisbenzothiazolylquinazoline… read more here.
