Lithium liq. ammonia Reactions with tert-hniyl thioethers Synthesis of hydrocarbons... 

A wide variety of fluorinated aromatic and polyaromatic systems are accessible via the BS synthesis, such as 11, 13, 16, and 18-21 presented earlier. Other examples are fluorinated mesitylenes,43 several polyfluorinated benzenes,44, 4-chloro-2-fluoronitro-benzene,4S bromofluorotoluenes,46 7-fluoroindanone, 8 fluorinated polycyclic aromatic hydrocarbons,17,47 4-tritylfluorobenzene,48 fluorinated diaryl thioethers, fluorophenols,50 fluoronorepinephrines, fluorinated estrogens,19,S2 and an unusual metacyclophane.53 A selection of these compounds is shown here.
