Strukturaufklärung von ausgewählten nitro‐ und sulfonsäuresubstituierten 1,2‐Naphthochinon‐2‐diaziden

Abstract

Structure Determination of Selected Nitro and Sulfonic Acid Substituted 1,2‐Naphthoquinone‐2‐diazidesSelected nitro derivatives of 1,2‐naphtoquinone‐2‐diazide 2 and 5 have been synthesized, the position of the NO₂‐group has been unambigously determined by means of ¹H and ¹³C n.m.r. spectroscopy, and the structure of these compounds has been comprehensively determined in relation to unsubstituted 1 and sulfonic acid substituted derivatives 3, 3a, 4 and 4a.Furthermore, the spectroscopical behaviour, especially in the uv/vis region, was examined in correlation to quantum chemical calculations.
