Abstract
![]()
Polyfluorinated biphenyls
are interesting and promising substrates
for many different applications. Unfortunately, all current methods
for the syntheses of these compounds only work for a hand full of
molecules or only in very special cases. Thus, many of these compounds
are still inaccessible to date. Here we report a general strategy
for the synthesis of a wide range of highly fluorinated biphenyls.
In our studies we investigated crucial parameters, such as different
phosphine ligands and the influence of various nucleophiles and electrophiles
with different degrees of fluorination. These results extend the scope
of the already very versatile Suzuki–Miyaura reaction toward
the synthesis of very electron-poor products, making these more readily
accessible. The presented methodology is scalable and versatile without
the need for elaborate phosphine ligands or Pd-precatalysts.
