Introduction of Fluorine and Fluorine‐Containing Functional Groups [PDF]

Angewandte Chemie - International Edition, 2013
AbstractOver the past decade, the most significant, conceptual advances in the field of fluorination were enabled most prominently by organo‐ and transition‐metal catalysis. The most challenging transformation remains the formation of the parent CF bond, primarily as a consequence of the high hydration energy of fluoride, strong metal—fluorine bonds ...
