Tetrakis(ethylene)irondilithium and Bis(η⁴‐1,5‐cy‐clooctadiene)irondilithium

Abstract

New FeLi 2 ‐olefin complexes , e.g. (1) , have been obtained from ferrocene by directed replacement of both C 5 H 5 ligands. (1) reacts with COD to give (COD) 2 FeLi 2 (2) [isolated as (2) ·2 DME or (2) ·2TMEDA]. which completes the series (COD) 2 Ni…(COD) 2 CoLi…(COD) 2 FeLi 2 equation image
