molecular oxygen and a catalytic amount of tris(pentane-2,4-dionato)iron(III), non-activated and moderately activated arenes, which include alkylbenzenes, halogenobenzenes, phenolic ethers, naphthalene and derivatives, can be nitrated with nitrogen dioxide at ice-bath temperature or below to give the corresponding nitro derivatives in fair to good yields. An electron-transfer mechanism has been proposed
在存在分子氧和催化量的三(戊烷-2,4-二价铁)(III)的情况下,可以将未活化和中度活化的芳烃(包括烷基苯,卤代苯,酚醚,萘和衍生物)进行硝化在冰浴温度或低于冰浴温度下用二氧化氮处理,以适当的收率得到相应的硝基衍生物。已经提出了电子转移机制,其中活化的NO 2 -Fe III络合物在将芳烃转化为硝基芳烃的循环过程中起关键作用。
