Trichloromethyl-substituted aromatic compounds are obtained by the chlorination of thioethers of the formula STR1 wherein Ar represents an optionally substituted aryl radial, X1 denotes hydrogen or halogen, and R1 represents optionally substituted alkyl, aralkyl, the nitrile group, an optionally substituted aryl radical or the group STR2 wherein Ar and X have the meaning given. The compounds, of which some are new, can be used as intermediate products for plant protection agents.

This invention pertains to a process for preparing substituted and unsubstituted benzotrichlorides. The process generally involves reacting the starting compound with a perchloroalkane with presence of base and a phase transfer catalyst.

A new method for converting benzyl and benzal chlorides to benzotrichlorides is reported.In contrast to prior art, the process involves contacting the substrates with strong alkali in a two-phase system containing phase transfer catalyst using organic soluble perchloralkanes acting upon base-generated carbanions.The method is particularly useful for preparing benzotrichlorides substituted by either alkyl or nitro groups.
