Polyhalogenonitrobenzenes and derived compounds part 4. Attempted fluorination of 1,2,3,4-tetrachloro-5,6-dinitrobenzene
Attempted fluorination of 1,2,3,4-tetrachloro-5,6-dinitrobenzene with potassium fluoride to give 1,2,3,4-tetrafluoro-5,6-dinitrobenzene in DMF or sulpholane, or under solid/liquid phase transfer conditions in toluene using Aliquat 336, TBAI or 18-Crown-6 failed to yield any products resulting from displacement of Cl by F. Rather surprisingly, the two products obtained were pentachloronitrobenzene and pentachlorofluorobenzene.

Aprotic diazotization in the presence of cuprous cyanide
In a procedure of extreme simplicity and rapidity a mixture of an aromatic primary amine, copper (I) cyanide and an alkyl nitrite in dimethyl sulphoxide yielded fair to moderate yields of the corresponding nitriles. Side processes observed were reduction (NH2&[H), nitration (NH2←NO2) and hydroxylation (NH2&[OH). In the case of polyhaloanilines halogen dance products could be detected.

Nitration of Strongly Deactivated Aromatics with Superacidic Mixed Nitric-Triflatoboric Acid (HNO3/2CF3SO3H-B(O3SCF3)3)
The nitration of various deactivated arenes (including methanesulfonyl-, nitro-, and polyhalobenzenes) was carried out in good yield with mixed nitric-triflatoboric superacid.For example pentafluorobenzene gave pentafluoronitrobenzene in 99percent yield, nitrobenzene to m-dinitrobenzene in 92percent selectivity with 85percent overall yield, and methyl phenyl sulfone gave only the m-nitro isomer in 78percent isolated yield.Thus the new nitrating system gives high regioselectivity and yields under generally mild reaction conditions.The reagent system is compatible with many functional groups of arenes.

Electrophilic Aromatic Substitution. Part 33. Kinetics and Products of Aromatic Nitrations in Solutions of Dinitrogen Pentaoxide in Nitric Acid
The kinetics and/or products of reaction, in nitric acid containing 0-5 mol dm-3 of dinitrogen pentaoxide, of phenyltrimethylammonium perchlorate, 1,2-dichloro-4-nitrobenzene, 2,4-dinitrotoluene, 1,4-dichloro-2-nitrobenzene, 1,2,4-trichloro-5-nitrobenzene, 1,2,4,5-tetrachlorobenzene, pentachlorobenzene, 1,2,3-trichlorobenzene, 1,3,5-trichloro-2-nitrobenzene, 1,2-dichloro-3-nitrobenzene, 1,2,3,4-tetrachlorobenzene, and 1,3-dichloro-2-nitrobenzene, have been studied.For each substrate investigated kinetically, rate coefficients for nitration in solutions containing more than ca. 2 mol dm-3 dinitrogen pentaoxide increase more quickly than the concentration of nitronium ion.In the cases of 1,2,4,5-tetrachlorobenzene, 1,4-dichloro-2-nitrobenzene, and 1,2,4-trichloro-5-nitrobenzene, but not with the other substrates, there was evidence for the formation of, in addition to expected aromatic nitroproducts, unstable cyclohexadiene products.Those from 1,2,4-trichloro-5-nitrobenzene were identified as a diastereomeric pair of 3,5,6-trichloro-2,4-dinitrocyclohexa-2,5-dienyl nitrates.A mechanism for the formation of these products is proposed.

Polyhalogenonitrobenzenes and Derived Compounds. Part 2. Reaction of 1,2,3,4-Tetrachloro-5,6-dinitrobenzene with Aliphatic Amines under Phasetransfer Conditions
The reactions of acyclic and cyclic aliphatic amines with 1,2,3,4-tetrachloro-5,6-dinitrobenzene have been investigated under phase-transfer conditions (toluene-water in the presence of Aliquat 336).In comparision with the corresponding reactions in toluene alone as solvent, overall reactivity increased, and there was an enhanced preference for chlorine rather than nitro-group displacement.An explanation for this is advanced.

Synthesis of C 14 labeled environment contaminants
Upon the reaction of benzene-14C via nitrobenzene-14C and aniline-14C, some 14C-labelled environmental contaminants were were synthesized. By chlorination of aniline-14C and acetanilide-14C the authors prepared chloroanilines-14C. Gomberg-Bachmann or Cadogan reaction of diazotated chloroanilines-14C with different chlorobenzenes gave di, tri- and pentachlorobiphenyls-14C. By boiling anilinediazonium sulfate-14C the authors prepared phenol-14C, which was chlorinated to give 2,4,6-trichlorophenol-14C. Hexachlorobenzene-14C and pentachloronitrobenzene-14C were prepared by chlorination of nitrobenzene- 14C. Chloralkylene 9-14C was synthesized by Friedel-Crafts alkylation of 2,4'-dichlorobiphenyl-14C with 2-chloropropane.
