A facile synthesis of ethyl 3,3,3-trifluoropropionate is described. Commercially available 2-bromo-3,3,3-trifluoropropene was used as a starting material, which was allowed to react with bromine to produce 2,2,3-tribromo-1,1,1-trifluoropropane. The resulting tribromide was treated with 3 equiv. of potassium ethoxide, giving rise to ethyl 3,3,3-trifluoropropionate in 60% overall yield in 2 steps. The reaction proceeded via an alkoxide-induced tandem reaction mechanism.

A new method is described for producing 3,3,3-trifluoroethyl isocyanate from perfluoroisobutene (PFIB). Isocyanate was used for synthesis of carbamates and ureas. A series of trifluoroethyl-substituted ureas has been tested in the National Cancer Institute (NCI, Bethesda, USA) by the NCI-60 DTP Human Tumor Cell Line Screening Program at a single high dose (10-5 M). The moderate anticancer activity was shown against some types of cancer on the individual human cell lines for leukemia, non-small cell lung cancer and renal cancer.
