Abstract

Radical chain fluoroalkylation of arenethiolates by CF3Br or CF2Cl2, performed under slight pressure in a glass a p pa rat u s, g ives a ry I po I yf I u o ro m et hy I s u I p h ides. ... Halogenoperfluoroalkanes (Freons) are noted for their inert- ness.' In the case of CF3Br and CF2C12, some reactivity has been observed when powerful nucleophilic reagents such as organolithium derivatives are used. These condensations often lead to partial (or even total) decomposition of the ...
