Nucleophilic addition to 2,3-pyridyne and synthesis of benzonaphthyridinones
摘要:
A study of the nucleophilic addition of amines to 2,3-pyridyne has been carried out. 2-Aminopyridines have been generated exclusively. A series of benzonaphthyridinones have been synthesized by reacting 2,3-pyridyne and o-aminobenzoates. (C) 2012 Elsevier Ltd. All rights reserved.

titanium complexes derived from 2-(2-ethylanilino)-, 2-(3,5-dimethylanilino)pyridine, 2-(4-n-butylanilino)- and 2-(2-t-butylanilino)pyridine were synthesized and characterized by spectroscopic methods. These complexes were used to catalyze the polymerization of ethylene in the presence of MAO as cocatalyst. The effect of the complex structures on the polymerization behavior was studied. All the alkylp
