f‐Block Phospholyl and Arsolyl Chemistry
1 Introduction The f-block elements, the lanthanides (Ln) and actinides (An), exhibit remarkable physicochemical properties that have spurred numerous curiosity-driven investigations and technological applications. 1 Organometallic f-block chemistry is predominated by cyclopentadienyl ligands (Cp, C 5 H 5) and their derivatives (Cp R, C 5 R 5), where one or more of the ring H atoms are ...
