摘要

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 ...
