Synthesis of Amino and Hydroxy Derivatives of 4,7-Phenanthroline

摘要

Nitro-,dinitro-,and hydroxynitrophenyl-substituted 4,7-phenanthrolines were reduced with tin(II) chloride in a mixture of acetic and nitric acids to obtain amino,diamino,and hydroxy derivatives of 4,7-phenanthroline.When heated with aromatic aldehydes,the products form azomethines of the 4,7-phen-anthroline series.
