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. |

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. |
