Monodentate ligands aromatic amines

The interaction between monodentate aliphatic and aromatic amines 156 takes place according to the same scheme, as well as diamine ligands, the spatial positions of the donor N atoms in which exclude the possibility of formation of chelate structures, for instance 160, 165, 166. In this respect, we note the synthesis of liquid amine complexes (diethyl- and triethylamine) with molybdenum dioxodichloride in hexane medium (3.9) [9] ...

However, the outcome of such reactions does depend on the entering ligand, as the above reaction performed with the aromatic monodentate amine pyridine instead of 1,2-ethanediamine leads to only four pyridines binding, with [V(py)4(S04)] as the product.

Four classes of catalysts have been used for the coupling of amines and related nitrogen nucleophiles witii aryl halides. Initially, complexes of the hindered monodentate aromatic tri-ortlio-tolylphosphine catalyzed the reaction of aryl bromides with secondary amines in the presence of an alkoxide or silylamide base. The use of this catalyst for this type of coupling to form C-N bonds was based on an earlier report of the reaction of aryl bromides with tin amides in the presence of a palladium complex of the same ligand as catalyst. - Later, complexes containing aromatic bisphosphines, such as BINAP and dppf, were...
