Chlorination and oxidation products formed from 1,2,4-trimethylbenzene in aqueous solution under the action of chlorine dioxide
Products of the reaction of 1,2,4-trimethylbenzene with chlorine dioxide in aqueous solution were studied. A scheme of 1,2,4-trimethylbenzene transformations was suggested. The influence exerted on the number of the reaction products by the ClO2 dosage and time of its contact with the substrate was examined.

Halogenation Using Quaternary Ammonium Polyhalides. XIX. Aromatic Chlorination of Arenes with Benzyltrimethylammonium Tetrachloroiodate
The reaction of arenes with a calculated amount of benzyltrimethylammonium tetrachloroiodate in acetic acid at room temperature or at 70 deg C gave nuclear chloro-substituted arenes in fairly good yields.
ELECTROPHILIC CHLORINATION OF 2,4,5-TRIMETHYLDIPHENYLMETHANE AND 1-(2,4,5-TRIMETHYLPHENYL)-1-PHENYLETHANE
The chlorination of 2,4,5-trimethyldiphenylmethane and 1-(2,4,5-trimethylphenyl)-1-phenylethane leads to the formation of the products from substitution of the hydrogen atoms at position 3 and 6 by chlorine and the products from ipso-substitution of the benzyl groups.
