For nearly 30 years trifluoromethyl‐substituted phosphanes were exclusively accessible by derivatization of the corresponding iodo compounds, which had to be synthesized in costly high‐pressure reactions in low yields. In many systems the replacement of the CF 3 group by the C 2 F 5 homologue provides a considerable increase in stability. In their Full Paper on page 12326 ff. B. Hoge and colleagues show that the aminophosphane C 2 F 5 P(NEt 2 ) 2 is accessible on a 40 g scale employing LiC 2 F 5 . The product represents a valuable starting material for a variety of pentafluoroethylphosphanes C 2 F 5 PX 2 (X=Br, H, F, OH).
