Cyclopropanation of trifluoromethyl(sulfinyl, sulfonyl) ethylenes was achieved by utilization of α-bromo- or α,α-dibromo 1,3-dicarbonyl compounds in the presence of bases. DBU was found to be the best choice to get good yields of cyclopropanes with CF3S(O)n (n = 1, 2) groups. First representatives of the cyclopropanes bearing trifluoromethylsulfinyl group were synthesized.

Heck reactions of perfluoroalkyl vinyl sulfoxides with aryl iodides are studied and palladium(II) acetate is shown to be the most convenient catalyst for this process. New E-1-aryl-2-perfluoroalkylsulfinylethylenes are synthesized. In all cases, by-products without a perfluoroalkylsulfinyl group are formed. (C) 2015 Elsevier Ltd. All rights reserved.
