Monocarbonyl complexes of iron(II): preparation and properties
Abstract
Iron(II) monocarbonyl complexes of the type [FeX(CO)L4]BPh4[X = Cl or Br; L = P(OMe)3′ P(OEt)3′ or PPh(OEt)2] and the dicarbonyl compound [FeBr(CO)2{PPh(OEt)2}3] BPh4 have been prepared and characterized by i.r.,1H and 31P-{1H} n.m.r. spectroscopy. Reactivity with some π-acceptor ligands has been investigated and synthesis of the new derivatives [FeBr(4-Me-C6H4NC)3L2]+[L = P(OMe)3′ P(OEt)3′ or PPh(OEt)2] achieved.
