Vinylidene fluoride has been successfully telomerized with carbon tetrachloride and perfluoro-t-butyl iodide as telogens; various new telomerization products and new compounds derived therefrom have been identified by NMR, IR, elemental analyses and chemical transformations. In agreement with our view that polar factors play an important part in deciding the orientation of free radical additions to vinylidene fluoride, it has been shown that the elcotrophilic radicals·CCl_3 and (CF_3)_3C·add to the methylene end of the alkene.Triethylamine has been used as the dehydrohalogenating agent in the following three reactions: (1) from CCl_3CH_2CF_2Cl (1) to the known compound CCl_12 = CHCF_2Cl (5); (2) from CCl_3CH_2CF_2CH_2CF_2Cl (6) to a mixture of CCl_2=CHCF_2CH_2CF_2Cl (7) and CCl_3 CH_2CF_2CH = CF_2 (8) ; and (3) from (CF_3)_3CCH_2CF_2I (3) to (CF_3)_3CCH = CF_2 (9).The reaction of diethylamine with the iodide 3 and (CF_3)_2CFCH_2CF_2I afforded the amides (CF_3)_3CCH_2CON (C_2H_5)_2 (10) and (CF_3)_2C=CH—CON (C_2H_5)_2 respectively. Dehydroiodination of 3 by KOH followed by hydrolysis yielded the perfluoro-t- butyl substituted acetic acid, (CF_3)_3CCH_2CO_2H(11).The exchange reaction of CCl_3CH_2CF_2Cl (1) with antimony fluorides was found to be able to proceed at relatively low temperature, fielding a mixture of CF_3CH_2CF_2Cl (18) and CF_2ClCH_2CF_2Cl (12). An unrearranged product, CCl_2=CHCF_3 (14) was obtained when the same reaction was applied to the alkene CCl_2 = CHCF_2Cl (5).The telomerization products Cl (CF_2CH_2)_nCCl_3 have been hydrolyzed in the strong acid medium to the corresponding carboxylic acids, Cl (CF_2CH_2)_nCOOH (n = 1~6).The alkaline salts of these acids Cl(CF_2CH_2)_nCOOM (n=3~5) have been proved to be good surfactants for emulsion polymerization of fluoro-olefins.

To establish the influence of the absolute configuration at the chiral centers of DV-acid on biological activities of the esters, each of their optical isomers was tested and compared in activity with certain reference compounds.In which, (+)-cis-isomer of the esters shows the highest activity, and is proved to be a potent insecticide.
