A variety of deactivated arenes were nitrated to their corresponding nitro derivatives in excellent yields under high-speed ball milling condition using Fe(NO3)3·9H2O/P2O5 as nitrating reagent. A radical involved mechanism was proposed for this facial, eco-friendly, safe, and effective nitration reaction.
使用Fe(NO 3)3 ·9H 2 O / P 2 O 5作为硝化剂,在高速球磨条件下,各种失活的芳烃都以极高的收率被硝化为相应的硝基衍生物。针对这种面部,生态友好,安全和有效的硝化反应,提出了一种涉及自由基的机制。

Nitration of benzonitrile was investigated using a nitricacid/acidanhydride/zeolite catalyst system under different reaction conditions. Trifluoroacetic and chloroacetic anhydrides were found to be the most active among the anhydrides tried. Also, zeolites Hβ and Fe3+β (Si/Al = 12.5) were found to be the most active catalysts. For example, nitration of benzonitrile with trifluoroacetyl nitrate under

The nitration of pivalophenone (2,2-dimethyl-1-phenyl-propan-1-one) with NO2BF4 gives o-, m-, and p-nitropivalophenones in the percentage ratio of 26:45:29. Competition experiments showed that pivalophenone is ten to twenty times less reactive than benzene but two to five times more reactive than acetophenone. No evidence for ipso attack could be found.
