用浸有 Bi(NO3 ) 3 的蒙脱土可区域选择性地硝化芳环化合物 ,硝化位置符合定位规律 (萘环以 α位为主 ,苯环以对位为主 ) ,但以酚为底物无选择性。 8例收率 72 %～ 99%。芳环硝化的一种简便方法@赵长阔 The aromatic compounds were selectively nitrated by montmorillonite soaked with Bi (NO3) 3. The nitration sites were in accordance with the localization rules (the naphthalene ring was mainly α, the benzene ring was mainly para), but phenol was the bottom No selectivity. 8 cases of the yield of 72% to 99%.
