The synthesis of trichloromethylphenyl sulfone derivatives as new potential pesticides is reported. The title sulfone was obtained in the four-step synthesis, starting from 4-chlorobenzene. and it was chlorosulfonated, reduced to the sulfinyl salt, which was transformed with chloroform to 4-chlorophenyldichloromethylsuIfone and in the next step with natrium hypohalite to the tide compound. TrichIoromethyl-4-chlorophenyl sulfone was nitrated and then subjected to the S'NAT reaction with ammonia, amines, hydrazine and other nucleophiles to give 2-nitroaniline and 2-nitrophenylhydrazine derivatives. After reduction of the nitro group - o-phenylenediamine derivative was obtained which was transformed into benzimidazole derivatives and other cyclic compounds. Characteristic IR spectroscopic data and microelementarv analyses of the new' products are reported.
