1-, 3-, and 6-nitrobenzo[a]pyrene in high yield. Comparison of the spectral data of these compounds with those obtained from direct nitration of benzo[a]pyrene confirmed that 1- and 3-nitrobenzo[a]pyrenes are indeed the minor products of the latter reaction. This confirmation also verifies that 1- and 3-nitrobenzo[a]pyrene were the minor nitrated products of benzo[a]pyrene formed in model air atmospheres
合成了诱变性环境污染物1-,3-和6-硝基苯并[a] re。在环境温度下用硝酸钠在三氟乙酸和乙酸酐中硝化7,8,9,10-四氢苯并[a] re,得到1-,3-和6-硝基-7,8,9,10-的混合物四氢苯并[a] py,通过色谱分离。用2,3-二氯-4,5-二氰基-1,6-苯醌对分离的硝基四氢苯并[a] py进行脱氢,可高产率地产生1-,3-和6-硝基苯并[a] py。将这些化合物的光谱数据与直接硝化苯并[a] py的光谱数据进行比较,证实1-和3-硝基苯并[a]]确实是后者反应的次要产物。该证实还证实1-和3-硝基苯并[a] py是在模型大气中形成的次要硝化的苯并[a] py的硝化产物。在鼠微粒体(S9)活化系统存在下,鼠伤寒沙门氏菌测试株TA98和TA100中的1-,3-和6-硝基苯并[a] re具有致突变性。在这些菌株中,1-硝基苯并[3-] py和6-硝基苯并[a] py均不是直接作
