The palladium-catalyzed chemoselective mono-amination of dichlorobenzenes was reported in this paper. Under the suitable conditions, all reactions involving the three isomers of dichlorobenzenes with various secondary and primary amines in the presence of

A Pd and norbornene-catalyzed ortho-arene amination via Catellani-type C-H functionalization is reported. Aryl halides are used as substrates; N-benzoyloxyamines and isopropanol are employed as the amine source (oxidant) and reductant respectively. Exampl

A new protocol for the Ullmann-type arylation process of different aromatic heterocycles without any transition-metal catalyst, implying the use of a combination of an excess of potassium hydroxide and dimethyl sulfoxide, is described. The reaction can be performed between a broad range of starting nucleophiles including phenol, alcohols, amines, nitrogen-containing five-membered systems such as pyrazoles, imidazoles, and indoles, and amides with haloarenes, iodide and bromide derivatives giving the best results, the possible pathway involving the in situ generation of the corresponding benzyne intermediate. When the reaction was performed with 2-iodoaniline and either carboxamides or isothiocyanato derivatives, the corresponding benzoazole derivatives were obtained.
