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.

A process for the preparation of a trichloromethyl-trifluoromethylbenzene of the formula STR1 wherein R1 and R2 are independently selected from the group consisting of hydrogen, fluorine, chlorine and bromine which comprises contacting a bis-(trichloromethyl)-benzene of the formula STR2 wherein R1 and R2 have the previously assigned significance with less than 6 mols of anhydrous hydrogen fluoride in the presence of a halogen transfer catalyst.
Method for preparing trichloromethyl-trifluoromethyl-benzenes
-
, (2008/06/13)
A process for the preparation of a trichloromethyl-trifluoromethyl-benzene of the formula STR1 wherein R1 and R2 are identical or different and represent hydrogen, fluorine or chlorine, By contacting at least one molecule of the formula STR2 wherein R1 and R2 are as previously identified, m and n are independently 0 to 3 With another molecule of the formula STR3 wherein M AND N ARE INDEPENDENTLY 0 TO 3 In the presence of a halogen transfer catalyst, optionally in the presence of a promoter.
