Synthesis of Polynitro-Substituted 2'-Nitrobiphenyl-2-Amines, Analogs of Polynitro Benzo[c]cinnoline Oxide Derivatives

Abstract

2',3,4',5- and 2',3,5,6'-Tetranitrobiphenyl-2-amines, and 2',3,4',5,6'- and 2',4,4',6,6'-pentanitrobiphenyl-2-amines, have been synthesized for the first time, along with the known 2,4,8- and 2,4,10-trinitrobenzo[c]cinnoline 6-oxides and 1,3,7,9-tetranitrobenzo [c]cinnoline 5- oxide. The benzocinnoline oxide derivatives were found to have higher densities and thermal stability than those of the corresponding biphenylamines. These observations are discussed in terms of structure.
