1,1-Bis(trifluoromethyl)alkyl isocyanates obtained from perfluoroisobutene (PFIB) react with aroyl(arylsulfonyl)hydrazines. Twenty eight prospective biologically active polyfluorinated 1,4-substituted semicarbazides were synthesized. The structure of each new product was confirmed by analytical and spectroscopic methods. The Lipinski's and Gelovani's parameters were then calculated. Two adjustments
number of perfluoromethacrylic acid derivatives have been prepared by the elimination of alkyl fluoride from substituted alkoxyperfluoroisobutylenes through the action of Lewis acids. Adducts (11a,b) containing a mesomeric carbonium-cation and a tetrafluoroborate-anion were obtained by reacting aminoacetals of bis(trifluoromethyl)ketene with BF3.

A number of N-bis(trifluoromethyl)alkyl-N'-thiazolyl and -benzothiazolyl ureas have been synthesized and evaluated for their in vitro antiproliferative activities against the human cancer cell lines at the National Cancer Institute (NCI, USA). The activity was shown for compounds 8a,c and 9a-c. The most sensitive cell lines relative to the tested compounds are: 8c PC-3 (prostate cancer, log GI(50) -7.10), 9c SNB-75 (CNS cancer, log GI(50) -5.84), 9b UO-31 (renal cancer, log GI(50) -5.66), and SR (leukemia, log GI(50) -5.44) human cancer cells.
