Fluonnated, preparation from fluonde

Instead of perchlorates, tnfluoromethanesulfonates (Inflates) can be used They are readily prepared and claimed to be safer than perchlorates [75] F Aryl fluondes have been prepared from p YC6H4N" (CH3)3CF3S03- (Y = COCqHs, CN, CHO, NO2, COCH3, CO2C2H5) by this alternative substrate Fluorodequaternization can also be applied to the preparation of fluonnated heterocyclics such as 4 fluoro 6 phenyl 1,3 pyrimidine [76] (equation 15) and fluoropunnes [77]... 

Mixtures of anhydrous hydrogen fluoride and tetrahydrofuran are successfully used as fluonnating agents to convert 1,1,2-trifluoro-l-alken-3-ols, easily prepared from bromotrifluoroethene via Iithiation followed by the reaction with aldehydes or ketones, to 1,1, l,2-tetrafluoro-2-alkenes The yields are optimal with a 5 1 ratio of hydrogen fluoride to tetrahydrofuran The fluonnation reaction involves a fluonde lon-induced rearrangement (Si>j2 mechanism) of allylic alcohols [65] (equation 40)...
