Synthesis and Reactivity of Iron-Iridium Heterobimetallic Complexes Using Tridentate Phosphine Ligands
Nawar, N. [نجوى نوار] ( Qatar University , 1994 , Article)Treatment of {Fe (CO)3 {(PPh2) 2 C=CH2}] with PPh2H gives the addition product [Fe (CO)3 {(PPh2) 2 CHCH2 PPh2}] (1). The uncoordinated phosphine group of complex 1 reacts with Ir4 (CO)12 to give mono-, di- and tri-substituted ...
