取代芳烃以天然皂土 / 4 0 %硝酸在己烷中催化硝化反应5 h,可高选择性地生成对位硝基衍生物 ,6例收率 35 %～99%。再以该体系进行苄位催化氧化生成相应的酮 ,5例收率 4 1%～ 90 .5 %。40%硝酸用于选择性单硝化和苄位氧化@王盈 The substituted aromatics could be converted to para-nitro derivatives with high selectivity by natural nitration of bentonite / 40% nitric acid in hexane for 5 h. The yield of six substituted nitroaromatics was 35% -99%. And then the system for catalytic oxidation of benzyl position to generate the corresponding ketones, 5 cases yield 4 1% ~ 90 .5%. 40% nitric acid for selective nitration and benzylic oxidation @ Wang Ying
