The nitriles CClF2CIS, CC12 (CN) 2, and CC13CiV have been fluorinated in a jet reactor under various conditions. The new saturated derivatives CCIFZCFZNF~, CC12FCF2NF2, CCl&! F2NF2, and CF~ CCLCF~ NFZ were formed, together with a product which has been tentatively assigned the structure iYF2CF2CC12CFzNF2. Also the interesting unsaturates CC1F2CF= iYF and CC13CF= NF were produced, as well as a related azo derivative and ...
