[交流] 求苯胺合成苯酚的资料(急)

求 2-甲基-6-硝基苯胺 通过重氮化水解后得  2-甲基-6-硝基苯酚的合成步骤    或者  从邻甲基苯酚 经硝化合成 2-甲基-6-硝基苯酚 的合成步骤
   相关文献也可以   

最好是发相关的文献给我

Nitration of some phenols and anilines under mild conditions.     Kashmiri, M. Akram; Khan, M. Shafiq.    Dep. Chem.,  Gov. Coll.,  Lahore,  Pak.    Science International (Lahore)  (1989),  1(3),  177-9.  CODEN: SINTE8  ISSN: 1013-5316.  Journal  written in English.    CAN 112:118358    AN 1990:118358    CAPLUS  

Abstract

Nitration of some phenols and anilines with 4-methyl-4-nitrotetrabromocyclohexadienone in ether under mild conditions is reported.  Resorcinol, pyrogallol, catechol, o-cresol, o- and m-toluidines gave 4-substituted products while hydroquinone, p-cresol, p-toluidine and phloroglucinol gave 2-substituted products.  Phenol and aniline both gave a mixt. of ortho and para substituted products.  While benzene, toluene, anisole and N,N-diethylanaline were not nitrated under the conditions.

Nitration of aromatic compounds with 4-methyl-4-nitro-2,3,5,6-tetrabromocyclohexadienone under mild conditions.     Kashmiri, M. Akram; Munawar, Munawar Ali; Yasmin, Rizwana; Khan, M. Shafiq.    Dep. Chem.,  Gov. Coll.,  Lahore,  Pak.    Journal of Natural Sciences and Mathematics  (1988),  28(2),  289-301.  CODEN: JNSMAC  ISSN: 0022-2941.  Journal  written in English.    CAN 111:57142    AN 1989:457142    CAPLUS  

Abstract

4-Methyl-4-nitrotetrabromocyclohexadienone in ether was successfully used for the mononitration of highly activated arom. substances which contain hydroxy and amino groups, at room temp.  For example, catechol, p-cresol, and aniline were converted into 4-nitrocatechol, 2-nitro-p-cresol, and 4-nitroaniline resp., in good yield.  In the case of phenol and aniline minor quantities of o-nitro derivs. were also obtained.  The results show that the reagent is very useful for the selective mononitration of arom. substrates which contain hydroxy or amine groups.  Two possible mechanisms, one involving charge-transfer complex formation and another one involving ion pair formation, are proposed.

总的路线: 1)2-甲基苯酚加发烟硫酸进行磺化(50度左右)2)然后硝化3)水蒸汽蒸馏即得你的产品。
我做过类似实验,我的产品是2-甲基-6-溴苯酚,我想对你有一定的参考价值。

p-Toluenesulfonic acid-catalyzed regiospecific nitration of phenols with metal nitrates.     Anuradha, V.; Srinivas, P. V.; Aparna, P.; Rao, J. Madhusudana.    Division of Organic Chemistry-I,  Indian Institute of Chemical Technology,  Hyderabad,  India.    Tetrahedron Letters  (2006),  47(28),  4933-4935.  Publisher: Elsevier B.V.,  CODEN: TELEAY  ISSN: 0040-4039.  Journal  written in English.    CAN 145:210693    AN 2006:598474    CAPLUS  

Abstract

Highly regiospecific mononitration of phenols and substituted phenols is accomplished employing a metal nitrate and a catalytic amt. of p-toluenesulfonic acid in acetone.  An exclusive ortho-selectivity was obsd. with excellent yields.  A variety of metal nitrates were used to obtain o-nitrophenols exclusively in good to excellent yields.  The use of p-toluenesulfonic acid is key for the selectivity obsd.
