The Chlorination of Some Substituted 2,4-Dimethylphenols

Autor: Jlm Gordon, Graeme J. Wright, RJ Martyn, Ward T. Robinson, M. P. Hartshorn, A. J. Morgan

Publikováno v: Australian Journal of Chemistry. 47:289

Chlorination reactions of 2-chloro-3,4,6-trimethylphenol (4), 2-chloro-4,6-dimethylphenol (5) and 3-chloro-2,4,6-trimethylphenol (6) are described. In acetic acid or acetic anhydride solution, chlorinations yield predominantly the corresponding 4-chl

The Mechanism and Stereochemistry of Chlorination of 2,4-Dichloro-3,,5,6-trimethylphenol and 2,4-Dichloro-3,6-dimethylphenol

Autor: Ward T. Robinson, M. P. Hartshorn, RJ Martyn, Graeme J. Wright, Jlm Gordon

Publikováno v: Australian Journal of Chemistry. 47:279

Electrophilic attack of chlorine on 2,4,6-trichloro-3,5,6-trimethylcyclohexa-2,4-dienone (2a) gives the trans-pentachloro ketones (3a) and (4a), while similar reaction of 2,4,6-trichloro-3,6-dimethylcyclohexa-2,4-dienone (2b) gives the trans- pentach

The Nitration of Tetrachlorocatechol and 3,4,6-Trichloro-5-methylcatechol. The Formation of 1-Hydroxycyclopent-3-enecarboxylic Acids

Autor: Ward T. Robinson, J. L. Calvert, Graeme J. Wright, M. P. Hartshorn, Jlm Gordon

Publikováno v: Australian Journal of Chemistry. 45:713

Reaction of tetrachlorocatechol (la) with nitric acid (d 1.48) gives the ring-contracted hydroxy dinitro acid (4), which was isolated as its ether solvate. Similar nitration of 3,4,6-trichloro-5-methylcatechol (lb) gives a mixture of stereoisomeric h
