Catalytic halodefluorination of aliphatic carbon-fluorine bonds

A variety of halosilanes, in conjunction with aluminum catalysts, convert fluorocarbons into higher halocarbons. Bromination and iodination of fluorocarbons are more effective than chlorination in terms of yield and activity. The mechanism for the reaction is investigated utilizing experimental and computational evidence and preliminary results suggest an alternate mechanism to that reported for the related hydrodefluorination reaction.

Process for the preparation of trichloromethyl-substituted aromatic compounds, and trichloromethyl-substituted aromatic compounds obtained in this process

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.

Process for preparing substituted benzotrichlorides

The invention herein pertains to a novel process for making substituted benzotrifluorides.

Method for converting carboxylic acid groups to trichloromethyl groups

Method for converting carboxylic acid groups to trichloromethyl groups which comprises contacting a compound containing a carboxylic acid group with a phenylphosphonic dichloride and phosphorus pentachloride and recovering the thus produced product.

α-Chlorination process

A process for α-chlorination of side chains of electronegatively substituted aromatic compounds with dichlorine monoxide.
