Abstract
Fig. 1. authors ascribe the corresponding structure, VIII. Oxidation of the dinitroditolyl, VIII, produced the dinitrodiphenic acid, IX, which can be esterified to form the methyl ester, V, of 2, 2'-dinitro-5, 5 '-dicarboxybiphenyl. Although the dinitro ester could thus be prepared, the yields we obtained by using the procedures of Case and Koft were low; a new and more convenient preparative method was therefore devised; this method depends upon the ...
